我在将Spring Boot应用程序部署到Websphere 8.5.5.9时遇到了很多问题，但这个让我感到有点难过。
当我通过我的CXF Rest端点调用时，我的Autowired JPARepository Bean获得了NullPointer，但是通过SpringBoot CommandLineRunner（）方法可以很好地插入数据。
项目代码可在github找到。
我将项目的类加载器配置为PARENT_LAST以使CXF正常工作，并设置了一个＆＃39; / cxf＆＃39;
的ContextRoot我可以看到应用正确加载，找到数据库＆amp;创建表等..
要点击端点我转到：host：port / cxf / services / sayHello / all
我正在从WebSphere中获取H2 JNDI数据源：
@Configuration
@EntityScan("com.was.spring.cxf.dto")
@EnableJpaRepositories(
entityManagerFactoryRef = "entityManagerFactory",
basePackages = { "com.was.spring.cxf.repository" })
@Order(1)
public class DSConfiguration {
private Logger logger = LoggerFactory.getLogger(DSConfiguration.class);
@Autowired
private Environment environment;
@Bean
public JndiObjectFactoryBean dataSourceFactoryBean() {
final JndiObjectFactoryBean jofb = new JndiObjectFactoryBean();
jofb.setJndiName("jdbc/ccbIntDataSource");
return jofb;
}
@Bean
@Primary
public DataSource dataSource() {
final Boolean initDB = false;
final DataSource dataSource = (DataSource) dataSourceFactoryBean().getObject();
//final Boolean initDB = environment.getProperty("init.db", Boolean.class, Boolean.FALSE);
logger.debug("Is initializing DB from sql scripts enabled? init.db={}", initDB);
if (initDB) {
logger.debug("Start initializing DB with scripts:");
final ResourceDatabasePopulator populator = new ResourceDatabasePopulator();
//populator.addScripts(dbInitScripts);
populator.setSqlScriptEncoding("UTF-8");
DatabasePopulatorUtils.execute(populator, dataSource);
logger.debug("End initializing DB");
}
return dataSource;
}
@Bean(name = "transactionManager")
public PlatformTransactionManager transactionManager(
@Qualifier("entityManagerFactory") EntityManagerFactory entityManagerFactory) {
return new JpaTransactionManager(entityManagerFactory);
}
@Bean
public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
return new PersistenceExceptionTranslationPostProcessor();
}
}
我设置了我的EMF：
@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages = "com.was.spring.cxf")
@Order(2)
public class JPAConfiguration {
private Logger logger = LoggerFactory.getLogger(JPAConfiguration.class);
@Autowired
private DataSource dataSource;
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
try {
logger.info("Using DataSource URL: " + dataSource.getConnection().getMetaData().getURL());
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
em.setDataSource(dataSource);
em.setPersistenceProviderClass(HibernatePersistence.class);
em.setPackagesToScan(new String[] { "com.was.spring.cxf.model", "com.was.spring.cxf.dto"});
JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
em.setJpaProperties(getHibernateProperties());
return em;
}
private Properties getHibernateProperties() {
Properties properties = new Properties();
properties.put("hibernate.dialect", H2Dialect.class.getName());
properties.put("hibernate.show_sql", "true");
properties.put("hibernate.hbm2ddl.auto", "create-drop");
return properties;
}
}
我有一个非常简单的界面＆amp;实施：
// Interface
@GET
@Path("/all")
@Produces(MediaType.APPLICATION_JSON)
Response getAllCustomers();
// Impl
@Override
public Response getAllCustomers() {
logger.info("INVOKING.....");
if (repository == null){
logger.info("REPO IS NULL....");
}
Iterable<Customer> customers = repository.findAll();
for (Customer customer : customers) {
logger.info(customer.toString());
}
return Response.status(Status.OK).entity(customers).build();
}
最后我有了Repository本身：
@Repository
public interface CustomerRepository extends JpaRepository<Customer, Long> {
List<Customer> findByLastName(String lastName);
}
但是当我尝试使用JPARepository时，我得到以下异常：
