java.sql.SQLSyntaxErrorException on a entity I'm not saving

there is a "insane" error on my spring boot application. I have two entities Arrecadacao and ArrecadacaoTest. They are mapped each with different tables. As you can see in the example, I'm trying to save an ArrecadacaoTest object.
I don't no why, but If I get an Arrecadacao object, set an attribute and DON'T SAVE it, I get an error saving ArrecadacaoTest.
They don't have any relation with each other.
In addition to it, it seems that the same code works at another computers.
Oracle database, java open jdk 1.8. What more can I say?
public void testeMulta(int idAit, int nrAnoAit) {
Arrecadacao multa = multasSrv.getMulta(idAit, nrAnoAit);
multa.setNrNossonumero("1234567890");
testeprsistencia();
}
#Transactional
public void testeprsistencia() {
ArrecadacaoTest arrecadacaoTest = new ArrecadacaoTest();
arrecadacaoTest.setIdArrecadacao(123457l);
arrecadacaoTest.setNrNossonumero("1234567890");
System.out.println(arrecadacaoTest);
arrecadacaoTestRepository.save(arrecadacaoTest);
System.out.println(arrecadacaoTest);
}
Console:

If I simply comment the set line, everything works
public void testeMulta(int idAit, int nrAnoAit) {
Arrecadacao multa = multasSrv.getMulta(idAit, nrAnoAit);
//multa.setNrNossonumero("1234567890");
testeprsistencia();

You have inconsistency between entity and table.
Column nrNossonumero is numeric, but in the entity is String.

#Andreas figureit out
When you update the fields of a JPA Entity object that was retrieved from the database, the changes will automatically be saved when the transaction is committed, without you having to call save(). Look at the stacktrace. You'll see that it doesn't include your method calling save(). Instead, it includes some Spring code calling JpaTransactionManager.doCommit()
So, my entity Arrecadacao was wrong, and for it wouldn't matter since I wasn't saving.
Thanks

Operation timed out. Spring batch

I faced with problem on my local machine (When start in on server it is ok).
My config
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.hikari.validation-timeout=30000
spring.datasource.hikari.minimumIdle=50

I tried different settings for connection pool. I thought this error related using another datasource for JobRepository, but he use is the same datasource. I tried annotation #Transactional

If you are using MySQL version greater than 5.0 use any one of the following dialect:
org.hibernate.dialect.MySQL5Dialect
org.hibernate.dialect.MySQL55Dialect
org.hibernate.dialect.MySQL57Dialect

GET http://myserverip:8081/myapp/api/v1/campaigns 500 (Internal Server Error)

I am having some strange issue, my spring boot app works just fine on localhost, but, when deploying it on the server, sometimes it loads data just fine, but I get 500 error occasionally, it's on the pages where I display data from mysql using angularJS.
Has anyone experienced a similar issue?
Below is my application.properties file:
spring.jpa.hibernate.ddl-auto=update
# Replace with your connection string
spring.datasource.url=jdbc:mysql://localhost:3306/myapp
spring.datasource.connectionProperties=useUnicode=true;characterEncoding=utf-8;
# Replace with your credentials
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.test-while-idle=true
spring.datasource.test-on-borrow=true
spring.datasource.connection-test-query=SELECT 1
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
And here is the log ( sry because it's long ):

I believe I have resolved the issue by adding new dependencies to my pom.xml file, and editing application.properties file as shown below:
spring.jpa.hibernate.ddl-auto=update
# Replace with your connection string
spring.datasource.url=jdbc:mysql://localhost:3306/myapp
spring.datasource.connectionProperties=useUnicode=true;characterEncoding=utf-8;

spring.datasource.username=root
spring.datasource.password=root
#spring.datasource.test-while-idle=true
# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
spring.datasource.test-on-borrow=true
spring.datasource.connection-test-query=SELECT 1
spring.datasource.tomcat.validation-interval=0
# Number of ms to wait before throwing an exception if no connection is available.
spring.datasource.tomcat.max-wait=10000
# Validate the connection before borrowing it from the pool.
spring.datasource.tomcat.test-on-borrow=true
#spring.datasource.driverClassName=com.mysql.jdbc.Driver
#spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
