TransactionRequiredException：没有事务正在进行JPA 2和JpaRepository

时间：2013-04-01 22:22:17

标签： spring transactions spring-data-jpa

我想将JPA与Spring数据一起使用。

        transaction-type="RESOURCE_LOCAL">

    </persistence-unit>

</persistence>

实体类

package net.betlista.tests.jpa.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table( name = "PERSON" )
public class Person {

    @Id
    @GeneratedValue
    private Long id;

    @Column
    private String name;

    @Column
    private int age;

    public Long getId() {
        return this.id;
    }

    public void setId( final Long id ) {
        this.id = id;
    }

    public String getName() {
        return this.name;
    }

    public void setName( final String name ) {
        this.name = name;
    }

    public int getAge() {
        return this.age;
    }

    public void setAge( final int age ) {
        this.age = age;
    }

}

服务

package net.betlista.tests.jpa.service;

import net.betlista.tests.jpa.entity.Person;

import java.util.List;

import org.springframework.stereotype.Service;

@Service
public interface IPersonService {

    List<Person> getAll();

    Person create( Person p );

}

实施

package net.betlista.tests.jpa.service;

import net.betlista.tests.jpa.dao.IPersonRepository;
import net.betlista.tests.jpa.entity.Person;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class PersonService implements IPersonService {

    @Autowired
    IPersonRepository personRepository;

    // @Autowired
    // EntityManagerFactory entityManagerFactory;

    @Override
    public List<Person> getAll() {
        return this.personRepository.findAll();
    }

    @Transactional
    @Override
    public Person create( final Person p ) {
        // final EntityTransaction transaction = this.entityManagerFactory.createEntityManager().getTransaction();
        // transaction.begin();
        final Person savedPerson = this.personRepository.saveAndFlush( p );
        // transaction.commit();
        return savedPerson;

    }

}

存储库

package net.betlista.tests.jpa.dao;

import net.betlista.tests.jpa.entity.Person;

import org.springframework.data.jpa.repository.JpaRepository;

public interface IPersonRepository extends JpaRepository<Person, Long> {

}

配置

package net.betlista.tests.jpa.dao;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@Configuration
@EnableJpaRepositories
@ComponentScan( "net.betlista.tests.jpa" )
@ImportResource( "classpath:applicationContext.xml" )
public class JavaConfig {

}

，最后测试

package net.betlista.tests.jpa2;

import net.betlista.tests.jpa.dao.JavaConfig;
import net.betlista.tests.jpa.entity.Person;
import net.betlista.tests.jpa.service.IPersonService;

import java.util.List;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration( classes = { JavaConfig.class } )
public class PersonServiceTest {

    @Autowired
    IPersonService personService;

    @Test
    public void testGetAll() {
        final List<Person> allPersons = this.personService.getAll();
        Assert.assertNotNull( allPersons );
        System.out.println( "person count: " + allPersons.size() );
    }

    @Test
    public void testCreate() {
        final Person person = new Person();
        person.setName( "B" );
        person.setAge( 22 );
        this.personService.create( person );
    }

}

为了验证HSQLDB问题的可能性，我迁移到了MySQL，我仍然遇到同样的问题。我刚刚更换了dataSource配置。

<bean>
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost:3306/person" />
    <property name="username" value="root" />
    <property name="password" value="pass" />
</bean>

1 个答案:

答案 0 :(得分：2)

我完全改变了配置。测试和目标是一样的。我写的时候改变了我的配置，这意味着persistence.xml和applicationContext.xml（服务，实体和存储库是相同的）。
