How to get rid of this exception " No bean named 'userDetailsService' is defined" although it is defined in xml file?

(edited from a previous version)
I created a simplified setting for your problem, and got the code to work.
Here are the two Java classes, first the service (in essense a stub, I did not try to simplify it further, the code has no particular significance):
package com.anzy.services;
import java.util.ArrayList;
import java.util.Collection;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
#Service("userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService
{
#Transactional(readOnly=true)
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException
{
Collection <GrantedAuthority> authorities=new ArrayList<GrantedAuthority>();
authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
org.springframework.security.core.userdetails.User secureUser=new org.springframework.security.core.userdetails.User("user", "user", true, true, true, true, authorities);
return secureUser;
}
}
and here is the controller (again, simplified to have just one method)
package com.anzy.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class DataController {
#RequestMapping("form")
public ModelAndView getForm() {
return new ModelAndView("form");
}
}
the four files under WEB-INF are:

You are getting NullPointerException in login method in UserManagedBean object. It is probably caused by null userService which might be injected in a wrong way. Try changing:
#ManagedProperty("#{UserService}")
to:
#ManagedProperty("#{userService}")

#Autowired
private CustomerService customerService;

Spring Boot Multiple Datasource

I'm quite new to spring boot and I'd like to create a multiple datasource for my project.
Here is my current case. I have two packages for entity for multiple database. Let's say
com.test.entity.db.mysql ; for entities that belong to MySql
com.test.entity.db.h2 ; for entities that belong to H2 Databases
So, currently I have two entities class
UserMySql.java
#Entity
#Table(name="usermysql")
public class UserMysql{
#Id
#GeneratedValue
public int id;
public String name;
}
UserH2.java
#Entity
#Table(name="userh2")
public class Userh2 {
#Id
#GeneratedValue
public int id;
public String name;
}
I'd like to achieve a configuration where if I create user from UserMySql, it will be saved to MySql Database, and if I create user from Userh2 it will be saved to H2 Databases. So, I also have two DBConfig, let's say MySqlDbConfig and H2DbConfig.
(com.test.model is package where I'll put my Repositories class. It will be defined below)
MySqlDbConfig.java
#Configuration
#EnableJpaRepositories(
basePackages="com.test.model",
entityManagerFactoryRef = "mysqlEntityManager")
public class MySqlDBConfig {
#Bean
#Primary
#ConfigurationProperties(prefix="datasource.test.mysql")
public DataSource mysqlDataSource(){
return DataSourceBuilder
.create()
.build();
}
#Bean(name="mysqlEntityManager")
public LocalContainerEntityManagerFactoryBean mySqlEntityManagerFactory(
EntityManagerFactoryBuilder builder){
return builder.dataSource(mysqlDataSource())
.packages("com.test.entity.db.mysql")
.build();
}
}
H2DbConfig.java
#Configuration
#EnableJpaRepositories(
entityManagerFactoryRef = "h2EntityManager")
public class H2DbConfig {
#Bean
#ConfigurationProperties(prefix="datasource.test.h2")
public DataSource h2DataSource(){
return DataSourceBuilder
.create()
.driverClassName("org.h2.Driver")
.build();
}
#Bean(name="h2EntityManager")
public LocalContainerEntityManagerFactoryBean h2EntityManagerFactory(
EntityManagerFactoryBuilder builder){
return builder.dataSource(h2DataSource())
.packages("com.test.entity.db.h2")
.build();
}
}
My application.properties file
#DataSource settings for mysql
datasource.test.mysql.jdbcUrl = jdbc:mysql://127.0.0.1:3306/test
datasource.test.mysql.username = root
datasource.test.mysql.password = root
datasource.test.mysql.driverClassName = com.mysql.jdbc.Driver
#DataSource settings for H2
datasource.test.h2.jdbcUrl = jdbc:h2:~/test
datasource.test.h2.username = sa
# DataSource settings: set here configurations for the database connection
spring.datasource.url = jdbc:mysql://127.0.0.1:3306/test
spring.datasource.username = root
spring.datasource.password = root
spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.datasource.validation-query=SELECT 1
# Specify the DBMS
spring.jpa.database = MYSQL
# Show or not log for each sql query
spring.jpa.show-sql = true
# Hibernate settings are prefixed with spring.jpa.hibernate.*
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.naming_strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.hibernate.show_sql = true
spring.jpa.hibernate.format_sql = true
server.port=8080
endpoints.shutdown.enabled=false
And then for crud I have UserMySqlDao and UserH2Dao
UserMySqlDao.java
#Transactional
#Repository
public interface UserMysqlDao extends CrudRepository<UserMysql, Integer>{
public UserMysql findByName(String name);
}
UserH2Dao.java
#Transactional
#Repositories
public interface UserH2Dao extends CrudRepository<Userh2, Integer>{
public Userh2 findByName(String name);
}
And for last, I have an UserController as endpoint to access my service
UserController.java
#Controller
#RequestMapping("/user")
public class UserController {
#Autowired
private UserMysqlDao userMysqlDao;
#Autowired
private UserH2Dao userH2Dao;
#RequestMapping("/createM")
#ResponseBody
public String createUserMySql(String name){
UserMysql user = new UserMysql();
try{
user.name = name;
userMysqlDao.save(user);
return "Success creating user with Id: "+user.id;
}catch(Exception ex){
return "Error creating the user: " + ex.toString();
}
}
#RequestMapping("/createH")
#ResponseBody
public String createUserH2(String name){
Userh2 user = new Userh2();
try{
user.name = name;
userH2Dao.save(user);
return "Success creating user with Id: "+user.id;
}catch(Exception ex){
return "Error creating the user: " + ex.toString();
}
}
}
Application.java
#Configuration
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
#EntityScan(basePackages="com.test.entity.db")
#ComponentScan
public class Application {
public static void main(String[] args) {
System.out.println("Entering spring boot");
ApplicationContext ctx = SpringApplication.run(Application.class, args);
System.out.println("Let's inspect the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.print(beanName);
System.out.print(" ");
}
System.out.println("");
}
}
With this configuration my Spring boot run well, but when I access
http://localhost/user/createM?name=myname it writes an exception
Error creating the user: org.springframework.dao.InvalidDataAccessResourceUsageException: could not execute statement; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not execute statement
I've googling around and haven't got a solution yet. Any ideas why this exception occurs? And is this the best way to implement multiple datasource to implement my case above? I'm open to full refactor if needed.
Thanks

I think you can find it usefull
http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-two-datasources
It shows how to define multiple datasources & assign one of them as primary.
Here is a rather full example, also contains distributes transactions - if you need it.
http://fabiomaffioletti.me/blog/2014/04/15/distributed-transactions-multiple-databases-spring-boot-spring-data-jpa-atomikos/
What you need is to create 2 configuration classes, separate the model/repository packages etc to make the config easy.
Also, in above example, it creates the data sources manually. You can avoid this using the method on spring doc, with #ConfigurationProperties annotation. Here is an example of this:
http://xantorohara.blogspot.com.tr/2013/11/spring-boot-jdbc-with-multiple.html
Hope these helps.

I faced same issue few days back, I followed the link mentioned below and I could able to overcome the problem
http://www.baeldung.com/spring-data-jpa-multiple-databases

I solved the problem (How to connect multiple database using spring and Hibernate) in this way, I hope it will help :)
NOTE: I have added the relevant code, kindly make the dao with the help of impl I used in the below mentioned code.

Update 2018-01-07 with Spring Boot 1.5.8.RELEASE
If you want to know how to config it, how to use it, and how to control transaction. I may have answers for you.
You can see the runnable example and some explanation in https://www.surasint.com/spring-boot-with-multiple-databases-example/
I copied some code here.
First you have to set application.properties like this
#Database
database1.datasource.url=jdbc:mysql://localhost/testdb
database1.datasource.username=root
database1.datasource.password=root
database1.datasource.driver-class-name=com.mysql.jdbc.Driver
database2.datasource.url=jdbc:mysql://localhost/testdb2
database2.datasource.username=root
database2.datasource.password=root
database2.datasource.driver-class-name=com.mysql.jdbc.Driver
Then define them as providers (#Bean) like this:
#Bean(name = "datasource1")
#ConfigurationProperties("database1.datasource")
#Primary
public DataSource dataSource(){
return DataSourceBuilder.create().build();
}
#Bean(name = "datasource2")
#ConfigurationProperties("database2.datasource")
public DataSource dataSource2(){
return DataSourceBuilder.create().build();
}
Note that I have #Bean(name="datasource1") and #Bean(name="datasource2"), then you can use it when we need datasource as #Qualifier("datasource1") and #Qualifier("datasource2") , for example
#Qualifier("datasource1")
#Autowired
private DataSource dataSource;
If you do care about transaction, you have to define DataSourceTransactionManager for both of them, like this:
#Bean(name="tm1")
#Autowired
#Primary
DataSourceTransactionManager tm1(#Qualifier ("datasource1") DataSource datasource) {
DataSourceTransactionManager txm = new DataSourceTransactionManager(datasource);
return txm;
}
#Bean(name="tm2")
#Autowired
DataSourceTransactionManager tm2(#Qualifier ("datasource2") DataSource datasource) {
DataSourceTransactionManager txm = new DataSourceTransactionManager(datasource);
return txm;
}
Then you can use it like
#Transactional //this will use the first datasource because it is #primary
or
#Transactional("tm2")
This should be enough. See example and detail in the link above.

Use multiple datasource or realizing the separation of reading & writing.
you must have a knowledge of Class AbstractRoutingDataSource which support dynamic datasource choose.
Here is my datasource.yaml and I figure out how to resolve this case. You can refer to this project spring-boot + quartz. Hope this will help you.
dbServer:
default: localhost:3306
read: localhost:3306
write: localhost:3306
datasource:
default:
type: com.zaxxer.hikari.HikariDataSource
pool-name: default
continue-on-error: false
jdbc-url: jdbc:mysql://${dbServer.default}/schedule_job?useSSL=true&verifyServerCertificate=false&useUnicode=true&characterEncoding=utf8
username: root
password: lh1234
connection-timeout: 30000
connection-test-query: SELECT 1
maximum-pool-size: 5
minimum-idle: 2
idle-timeout: 600000
destroy-method: shutdown
auto-commit: false
read:
type: com.zaxxer.hikari.HikariDataSource
pool-name: read
continue-on-error: false
jdbc-url: jdbc:mysql://${dbServer.read}/schedule_job?useSSL=true&verifyServerCertificate=false&useUnicode=true&characterEncoding=utf8
username: root
password: lh1234
connection-timeout: 30000
connection-test-query: SELECT 1
maximum-pool-size: 5
minimum-idle: 2
idle-timeout: 600000
destroy-method: shutdown
auto-commit: false
write:
type: com.zaxxer.hikari.HikariDataSource
pool-name: write
continue-on-error: false
jdbc-url: jdbc:mysql://${dbServer.write}/schedule_job?useSSL=true&verifyServerCertificate=false&useUnicode=true&characterEncoding=utf8
username: root
password: lh1234
connection-timeout: 30000
connection-test-query: SELECT 1
maximum-pool-size: 5
minimum-idle: 2
idle-timeout: 600000
destroy-method: shutdown
auto-commit: false

Using two datasources you need their own transaction managers.
#Configuration
public class MySqlDBConfig {
#Bean
#Primary
#ConfigurationProperties(prefix="datasource.test.mysql")
public DataSource mysqlDataSource(){
return DataSourceBuilder
.create()
.build();
}
#Bean("mysqlTx")
public DataSourceTransactionManager mysqlTx() {
return new DataSourceTransactionManager(mysqlDataSource());
}
// same for another DS
}
And then use it accordingly within #Transaction
#Transactional("mysqlTx")
#Repository
public interface UserMysqlDao extends CrudRepository<UserMysql, Integer>{
public UserMysql findByName(String name);
}

Thanks all for your help but it is not complicated as it seems; almost everything is handled internally by SpringBoot.
In my case I want to use Mysql and Mongodb and the solution was to use EnableMongoRepositories and EnableJpaRepositories annotations on to my application class.
#SpringBootApplication
#EnableTransactionManagement
#EnableMongoRepositories(includeFilters = #ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MongoRepository))
#EnableJpaRepositories(excludeFilters = #ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MongoRepository))
class TestApplication { ...
NB: All mysql entities have to extend JpaRepository and mongo enities have to extend MongoRepository.
The datasource configs are straight forward as presented by spring documentation:
//mysql db config
spring.datasource.url= jdbc:mysql://localhost:3306/tangio
spring.datasource.username=test
spring.datasource.password=test
#mongodb config
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=tangio
spring.data.mongodb.username=tangio
spring.data.mongodb.password=tangio
spring.data.mongodb.repositories.enabled=true

once you start work with jpa and some driver is in your class path spring boot right away puts it inside as your data source (e.g h2 )
for using the defult data source therefore u will need only to define
spring.datasource.url= jdbc:mysql://localhost:3306/
spring.datasource.username=test
spring.datasource.password=test
if we go one step farther and u want to use two
I would reccomend to use two data sources such as explained here :
Spring Boot Configure and Use Two DataSources
