Managed Bean无法自动装配Spring服务
我可以在JSF Managed Bean中自动装配Spring @Repository类，但不能自动装配@Service类，问题是什么？
的 LoginBean.java
@ManagedBean(name = "loginBean")
@ViewScoped
public class LoginBean implements Serializable
{
private String username;
private String password;
@Autowired
private AccountService accountService;
public LoginBean()
{
}
@PostConstruct
public void init()
{
FacesContextUtils.getRequiredWebApplicationContext(FacesContext.getCurrentInstance()).getAutowireCapableBeanFactory().autowireBean(this);
// springBeanName is now available.
}
}
如果我自动装配存储库类，一切都运行良好，但如果我将服务类自动装配为上面的代码，则会发生错误。这是完整的错误堆栈：

这是我的服务类
的 AccountService.java
@Service
@Transactional(readOnly = true)
public class AccountService
{
//@ManagedProperty("#{accountRepository}")
@Autowired
private AccountRepository accountRepository;
public AccountRepository getRepository()
{
return accountRepository;
}
public void save(Account entity)
{
accountRepository.save(entity);
}
}
这是我的项目结构
我正在使用javaconfig进行配置，这是我的配置：
的 PersistenceContext.java
@Configuration
@EnableJpaRepositories(basePackages ={"com.peter.uass"})
//@EnableJpaRepositories(basePackages ={"com.peter.uass.repository", "com.peter.uass.service"})
//@EnableJpaRepositories("com.peter.uass.repository")
@EnableTransactionManagement
@PropertySource("classpath:application.properties")
public class PersistenceContext
{
@Bean(destroyMethod = "close")
DataSource dataSource(Environment env)
{
HikariConfig dataSourceConfig = new HikariConfig();
dataSourceConfig.setDriverClassName(env.getRequiredProperty("db.driver"));
dataSourceConfig.setJdbcUrl(env.getRequiredProperty("db.url"));
dataSourceConfig.setUsername(env.getRequiredProperty("db.username"));
dataSourceConfig.setPassword(env.getRequiredProperty("db.password"));
return new HikariDataSource(dataSourceConfig);
}
@Bean
LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, Environment env)
{
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource);
entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
entityManagerFactoryBean.setPackagesToScan("com.peter.uass");
Properties jpaProperties = new Properties();
jpaProperties.put("hibernate.dialect", env.getRequiredProperty("hibernate.dialect"));
jpaProperties.put("hibernate.hbm2ddl.auto", env.getRequiredProperty("hibernate.hbm2ddl.auto"));
jpaProperties.put("hibernate.ejb.naming_strategy", env.getRequiredProperty("hibernate.ejb.naming_strategy"));
jpaProperties.put("hibernate.show_sql", env.getRequiredProperty("hibernate.show_sql"));
jpaProperties.put("hibernate.format_sql", env.getRequiredProperty("hibernate.format_sql"));
entityManagerFactoryBean.setJpaProperties(jpaProperties);
return entityManagerFactoryBean;
}
@Bean
JpaTransactionManager transactionManager(EntityManagerFactory entityManagerFactory)
{
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory);
return transactionManager;
}
}
我的WebAppInitializer.java为空，我使用web.xml进行配置 的的web.xml
<context-param>
<param-name>contextClass</param-name>
<param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
</context-param>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>com.peter.uass.config</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<listener>
<listener-class>
org.springframework.web.context.request.RequestContextListener
</listener-class>
</listener>
