我想知道如何在SpringRESTWebService中控制事务。如果我在不使用WebserviceController的情况下使用JUnit-to-Service和DAO进行测试，就可以了。但是，当客户端程序调用webservice进程时，我得到以下错误

环境

配置Tomcat 7需要做什么

错误

Client.java

RestTemplate restTemplate = new RestTemplate();
OperatorDTO operatorDTO = new OperatorDTO("CycDemo", "TTF", "01234684101");
String response = restTemplate.postForObject(SERVER_URI + URIConstant.OPERATOR_CREATE, operatorDTO, String.class);

服务器端

OperatorController.java

@Controller
public class OperatorController {
    @Autowired
    private IOperatorService operatorService;

    @RequestMapping(value = URIConstant.OPERATOR_CREATE, method = RequestMethod.POST, produces = "application/json; charset=utf-8")
    public @ResponseBody OperatorDTO createOperator(@RequestBody OperatorDTO operatorDTO) {
        Operator operator = new Operator(operatorDTO);
        operatorService.addNewOperator(operator);
        return operatorDTO;
    }
}

OperatorService.java

@Service(value = "OperatorService")
public class OperatorService implements IOperatorService {
    @Resource(name = "OperatorDAO")
    private IOperatorDAO OperatorDAO;

    @Transactional(propagation = Propagation.REQUIRED)
    public void addNewOperator(Operator Operator) throws SystemException {
        try {
            OperatorDAO.insert(Operator);
        } catch (DAOException e) {
            //throw exception
        }
    }   
}

OperatorDAO.java

@Repository("OperatorDAO")
public class OperatorDAO implements IOperatorDAO {
    // inject entity manager

    @Transactional(propagation = Propagation.REQUIRED)
    public void insert(Operator operator) throws DAOException {
        try {
            em.persist(operator);
            em.flush();
        } catch (PersistenceException pe) {
            //throw exception
        }
    }

我有一个解决办法。现在，一切都好了

我更改配置如下

servlet-context.xml

<annotation-driven />
<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
<resources mapping="/resources/**" location="/resources/" />

<!-- Configure to plugin JSON as request and response in method handler -->
<beans:bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
    <beans:property name="messageConverters">
        <beans:list>
            <beans:ref bean="jsonMessageConverter"/>
        </beans:list>
    </beans:property>
</beans:bean>

<!-- Configure bean to convert JSON to POJO and vice versa -->
<beans:bean id="jsonMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
</beans:bean>
