问题：
添加spring-batch依赖项时spring-repository保存不起作用？
王凌
在WebSphere8.5.5.13上部署了Spring4+JPA应用程序，在数据库中保存了JPA。所以，在我添加了spring-batch之后，我面临着jpa实体无法保存的问题。
所以，在事务管理器配置中的原因就像这里，如果我添加了事务管理器-JPA也尝试使用它。
@Configuration
@EnableWebMvc
@EnableBatchProcessing
@ComponentScan(basePackages = {"config"})
@PropertySource("classpath:application.properties")
public class WebAppInitalizer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
rootContext.register(
WebConfig.class,
ServiceConfig.class,
PersistenceConfig.class,
BatchConfig.class
);
....
}
record = new UserRecord(name, surname, age, updateDateTime, serialize(UserToSave));
@Entity
@Audited
@Table(name = "UserRecord")
@NoArgsConstructor(access = AccessLevel.PUBLIC)
@AllArgsConstructor
@Getter
@Setter
@Access(AccessType.FIELD)
public class UserRecord {
@Id
@GeneratedValue(generator = "uuid")
@GenericGenerator(name = "uuid", strategy = "uuid2")
@Column(name = "PR_KEY")
private String prKey;
//Business Key
@Column(name = "name", length = 100, unique = false)
private String name;
//Business Key
@Column(name = "surname", length = 100, nullable = false)
private String surname;
//Business Key
@Column(name = "age", length = 100, nullable = false)
private int age;
@Column(name = "updateDateTime", length = 50, nullable = false)
private Timestamp updateDateTime;
@Version
private int version;
@Column(name = "user", length = 100000)
@Lob

public UserRecord(String name, String surname, String age, Timestamp updateDateTime, byte[] user) {
this.name = name;

这是图书馆的问题？（我试着注释所有的spring-batch代码，在pom中只保留depedency，然后它开始工作了。
我与数据库相关的bean是：
@Configuration
@EnableTransactionManagement
@EnableJpaAuditing
@EnableJpaRepositories(basePackages = {"persistence"})
@ComponentScan(basePackages = {"persistence""})
public class PersistenceConfig {
@Bean
@Resource(type = DataSource.class, lookup = "jdbc/MyDataBase", name = "jdbc/MyDataBase")
public DataSource dataSource() {
final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
dsLookup.setResourceRef(true);
DataSource dataSource = dsLookup.getDataSource("java:comp/env/jdbc/MyDataBase");
return dataSource;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManager = new LocalContainerEntityManagerFactoryBean();
entityManager.setDataSource(dataSource());
entityManager.setPackagesToScan(PACKAGE_WITH_JPA_ENTITIES);
entityManager.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
entityManager.setJpaProperties(getHibernateProperties());
log.info("Entity Manager configured.");
return entityManager;
}
@Bean
public JpaTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory);
return transactionManager;
}
//Set properties hibernate
private Properties getHibernateProperties() {
Properties properties = new Properties();
properties.put("hibernate.dialect", "org.hibernate.dialect.OracleDialect");
properties.put("hibernate.show_sql", "true");
properties.put("hibernate.hbm2ddl.auto", "none");
properties.put("org.hibernate.envers.do_not_audit_optimistic_locking_field", false);
properties.put("verifyServerCertificate", false);
properties.put("useSSL", false);
properties.put("requireSSL", false);
properties.put("useLegacyDatetimeCode", false);
properties.put("useUnicode", "yes");
properties.put("characterEncoding", "UTF-8");
properties.put("serverTimezone", "UTC");
properties.put("useJDBCCompliantTimezoneShift", true);
return properties;
}
}

Spring-batch工作，但不能保存jpa实体。

根本原因不是依赖关系冲突。原因是JPA和Spring-Batch有两个同名bean。因此，创建不同名称的bean就解决了一个问题。
@Bean
public ResourcelessTransactionManager springBatchTransactionManager() {
return new ResourcelessTransactionManager();
}
@Bean
public JobRepository jobRepository(ResourcelessTransactionManager springBatchTransactionManager) throws Exception {
MapJobRepositoryFactoryBean mapJobRepositoryFactoryBean = new MapJobRepositoryFactoryBean(springBatchTransactionManager);
mapJobRepositoryFactoryBean.setTransactionManager(springBatchTransactionManager);
return mapJobRepositoryFactoryBean.getObject();
}
