NPE in MySQLAdapter only in deployed jar - java

I am having issue when I deploy the jar in AWS ubuntu server,I have 2 packages in Spring Boot.
#1)core package
#2)Process package
The first package(core) is not containing spring boot dependency and generate the jar using maven package,When I run the code the below code works fine in Intellij. But when I deploy in AWS Ubuntu machine I get Null Pointer Exception for MySQLAdapter Class used in the Process PackageController.
Below is the code
//Code in Process
#SpringBootApplication
public class ProcessApplication
{
#Bean
MySQLAdapter mySQLAdapter() {
MySQLAdapter mySQLAdapter = new MySQLAdapter();
return mySQLAdapter;
}
public static void main(String[] args) {
SpringApplication.run(com.test.ProcessApplication.class, args);
}
}
// Core package jar
public class MySQLAdapter {
private String hostName;
private int port;
private String DBName;
private String username;
private String pwd;
private String secretPwdKey;
private com.test.Util.CryptoUtil cryptoUtil;
public MySQLAdapter() {
hostName = "localhost";
port = 3306;
username = "test";
pwd = "test";
DBName = "test";
secretPwdKey = "test";
cryptoUtil = new com.test.Util.CryptoUtil();
}
}
Is this Null Pointer Exception because of cryptoUtil not getting injected or instantiated?
How can this be solved?
// Controller inside Process package
#RestController
class MyRestController{
#Autowired
MySQLAdapter mySQLAdapter;
#RequestMapping(value = {"/register"}, method = {RequestMethod.POST}, produces = {"application/json"})
#ResponseBody
public RegistrationResponse register(#Valid #RequestBody UserPojo userPojo) {
if (!this.mySQLAdapter.checkClientID(userPojo.getClientID())) { //Null Pointer thrown here
}
}
}

How to Validate ui data with rest api responses

I need to validate my ui data and api responses are same,
here is my code I tried,
private ValidateContentPage cp = new ValidateContentPage();
public void getTitle() {
String UITitle = driver.findElement(titlepage).getText();
System.out.println(UITitle);
Assert.assertEquals(UITitle, cp.getAPICall(),"Passed");
}
here im getting my api responses,
public class ValidateContentPage {
public common cm = new common();
public Properties prop;
public void baseURI() {
prop = cm.getProperties("./src/test/API/IndiaOne/propertyfile/EndpointURL.properties");
RestAssured.baseURI = prop.getProperty("baseURI");
}
public String getAPICall() {
objectpojo ps = given().expect().defaultParser(Parser.JSON).when().get(prop.getProperty("resources")).as(objectpojo.class, cm.getMapper());
int number = ps.getPosts().size();
System.out.println(number);
System.out.println(ps.getPosts().get(0).getTitle());
return ps.getPosts().get(0).getTitle();
}
If i validate both using testng assertion it throwing null pointer exception, anyone help me on how to validate my ui data and api responses.
You need to call your ValidateContentPage from #Test itself or from #BeforeTest
#Test
public void getTitle() {
String UITitle = driver.findElement(titlepage).getText();
System.out.println(UITitle);
ValidateContentPage cp = new ValidateContentPage();
Assert.assertEquals(UITitle, cp.getAPICall(),"Passed");
}

How to spock integration test with standalone tomcat runner?

Our project is not currently using a spring framework.
Therefore, it is being tested based on the standalone tomcat runner.
However, since integration-enabled tests such as #SpringBootTest are not possible, Tomcat is operated in advance and the HTTP API test is carried out using Spock.
Is there a way to turn this like #SpringBootTest?
TomcatRunner
private Tomcat tomcat = null;
private int port = 8080;
private String contextPath = null;
private String docBase = null;
private Context rootContext = null;
public Tomcat8Launcher(){
init();
}
public Tomcat8Launcher(int port, String contextPath, String docBase){
this.port = port;
this.contextPath = contextPath;
this.docBase = docBase;
init();
}
private void init(){
tomcat = new Tomcat();
tomcat.setPort(port);
tomcat.enableNaming();
if(contextPath == null){
contextPath = "";
}
if(docBase == null){
File base = new File(System.getProperty("java.io.tmpdir"));
docBase = base.getAbsolutePath();
}
rootContext = tomcat.addContext(contextPath, docBase);
}
public void addServlet(String servletName, String uri, HttpServlet servlet){
Tomcat.addServlet(this.rootContext, servletName, servlet);
rootContext.addServletMapping(uri, servletName);
}
public void addListenerServlet(ServletContextListener listener){
rootContext.addApplicationListener(listener.getClass().getName());
}
public void startServer() throws LifecycleException {
tomcat.start();
tomcat.getServer().await();
}
public void stopServer() throws LifecycleException {
tomcat.stop();
}
public static void main(String[] args) throws Exception {
System.setProperty("java.util.logging.manager", "org.apache.logging.log4j.jul.LogManager");
System.setProperty(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "org.apache.naming.java.javaURLContextFactory");
System.setProperty(javax.naming.Context.URL_PKG_PREFIXES, "org.apache.naming");
Tomcat8Launcher tomcatServer = new Tomcat8Launcher();
tomcatServer.addListenerServlet(new ConfigInitBaseServlet());
tomcatServer.addServlet("restServlet", "/rest/*", new RestServlet());
tomcatServer.addServlet("jsonServlet", "/json/*", new JsonServlet());
tomcatServer.startServer();
}
Spock API Test example
class apiTest extends Specification {
//static final Tomcat8Launcher tomcat = new Tomcat8Launcher()
static final String testURL = "http://localhost:8080/api/"
#Shared
def restClient
def setupSpec() {
// tomcat.main()
restClient = new RESTClient(testURL)
}
def 'findAll user'() {
when:
def response = restClient.get([path: 'user/all'])
then:
with(response){
status == 200
contentType == "application/json"
}
}
}
The test will not work if the annotations are removed from the annotations below.
// static final Tomcat8Launcher tomcat = new Tomcat8Launcher()
This line is specified API Test at the top.
// tomcat.main()
This line is specified API Test setupSpec() method
I don't know why, but only logs are recorded after Tomcat has operated and the test method is not executed.
Is there a way to fix this?
I would suggest to create a Spock extension to encapsulate everything you need. See writing custom extensions of the Spock docs as well as the built-in extensions for inspiration.

Exception in combination of #DirtiesContext and FlywayConfig bean in integration test

Override Ribbon Server List to get a list of host names from consul

I am trying to override Ribbon Server List to get a list of host names from consul. I have the consul piece working properly(when testing with hardcode values) to get the hostname and port for a service. The issue I am having is when I try to autowire in IClientConfig. I get an exception that IClientConfig bean could not be found. How do I override the ribbon configurations and autowire IClientConfig in the ribbonServerList method.
I have tried following the instructions here at http://projects.spring.io/spring-cloud/spring-cloud.html#_customizing_the_ribbon_client on how to customize ribbon client configuration. I keep getting the following error:
Description:
Parameter 0 of method ribbonServerList in com.intradiem.enterprise.keycloak.config.ConsulRibbonSSLConfig required a bean of type 'com.netflix.client.config.IClientConfig' that could not be found.
Which is causing spring-boot to fail.
Bellow are the classes that I am trying to use to create
AutoConfiguration Class:
#Configuration
#EnableConfigurationProperties
#ConditionalOnBean(SpringClientFactory.class)
#ConditionalOnProperty(value = "spring.cloud.com.intradiem.service.apirouter.consul.ribbon.enabled", matchIfMissing = true)
#AutoConfigureAfter(RibbonAutoConfiguration.class)
#RibbonClients(defaultConfiguration = ConsulRibbonSSLConfig.class)
//#RibbonClient(name = "question-answer-provider", configuration = ConsulRibbonSSLConfig.class)
public class ConsulRibbonSSLAutoConfig
{
}
Configuration Class:
#Component
public class ConsulRibbonSSLConfig
{
#Autowired
private ConsulClient client;
private String serviceId = "client";
public ConsulRibbonSSLConfig() {
}
public ConsulRibbonSSLConfig(String serviceId) {
this.serviceId = serviceId;
}
#Bean
#ConditionalOnMissingBean
public ServerList<?> ribbonServerList(IClientConfig clientConfig) {
ConsulSSLServerList serverList = new ConsulSSLServerList(client);
serverList.initWithNiwsConfig(clientConfig);
return serverList;
}
}
ServerList Code:
public class ConsulSSLServerList extends AbstractServerList<Server>
{
private final ConsulClient client;
private String serviceId = "client";
public ConsulSSLServerList(ConsulClient client) {
this.client = client;
}
#Override
public void initWithNiwsConfig(IClientConfig clientConfig) {
this.serviceId = clientConfig.getClientName();
}
#Override
public List<Server> getInitialListOfServers() {

return getServers();
}
private List<Server> getServers() {
List<Server> servers = new ArrayList<>();

}
return servers;

Cassandra Migration Library in Java

I have created a Spring Boot microservice which runs aggregation on a stream of data and writes it into various Cassandra tables. I am looking for a java library similar to Flyway which will migrate Cassandra schema with the existence of a script in a resource folder. Does anyone have any recommendations, preferably for a library which you personally have used in production?
I used builtamont:
<dependency>
<groupId>com.builtamont</groupId>
<artifactId>cassandra-migration</artifactId>
<version>0.9</version>
</dependency>
migration in code:
import com.builtamont.cassandra.migration.CassandraMigration;
import com.builtamont.cassandra.migration.api.configuration.KeyspaceConfiguration;
import org.springframework.beans.factory.InitializingBean;
class CassandraDataSourceMigration implements InitializingBean {
private final String ip;
private final String clusterName;
private final Integer port;
private final String keyspaceName;
private final String migrationsPath;
public CassandraDataSourceMigration(String ip, String clusterName, Integer port, String keyspaceName, String migrationsPath) {
this.ip = ip;
this.clusterName = clusterName;
this.port = port;
this.keyspaceName = keyspaceName;
this.migrationsPath = migrationsPath;
}
// getters/setters
#Override
public void afterPropertiesSet() throws Exception {
final KeyspaceConfiguration keyspaceConfig = new KeyspaceConfiguration();
keyspaceConfig.setName(keyspaceName);
keyspaceConfig.getClusterConfig().setContactpoints(new String[]{ip});
if (port != null) {
keyspaceConfig.getClusterConfig().setPort(port);
}
final CassandraMigration migrationProcessor = new CassandraMigration();
migrationProcessor.setLocations(new String[]{migrationsPath});
migrationProcessor.setKeyspaceConfig(keyspaceConfig);
migrationProcessor.migrate();
}
}
application.properties
cassandra.ip=127.0.0.1
cassandra.cluster=My cluster
cassandra.keyspace=saya
cassandra.migration=classpath:db/migration
cassandra.port=9042
And the migration script is under resources/db/migration V1_0__Init_table.cql
