Java 没有MVC的restful服务

我想创建一个Restful服务，但当我尝试url“http..:8080/appanalyticx web/requirementservice/saverequirements”时，它不起作用

Myservice:

@Path("/requirementservice")
@Service("dimRequirementManager")
public class DimRequirementManagerImpl extends GenericManagerImpl<DimRequirement, Long> implements DimRequirementManager {
    DimRequirementDao dimRequirementDao;

    @Autowired
    public DimRequirementManagerImpl(DimRequirementDao dimRequirementDao) {
        super(dimRequirementDao);
        this.dimRequirementDao = dimRequirementDao;
    }
    @PUT
    @Path("/saverequirements")
    @Consumes("application/json")
    @Override
    public void saveAllDimRequirements(List<DimRequirement> requirementList) {
        dimRequirementDao.saveAllDimRequirements(requirementList);

    }
}

您必须有一个servlet，否则

@Path

注释将不起任何作用。

在

saveAllDimRequirements

方法中，您必须使用put，因为您有

@put

注释。

当然您需要一个servlet。你认为映射

@Path

注释应该是什么？在despacher servlet的帮助下，我可以从客户端访问该服务吗？因此我的URL将是http..:8080/project/Dispacher servletURL/requirementservice/SaveRequirements我建议你自己试试看。dispatcher org.springframework.web.servlet.Dispatchers servlet contextConfigLocation 2 dispatcher/restServices/*我添加了servlet我可以使用的确切url是什么？很可能类似于：

http://:8080//restServices/requirementservice/saverequirements

如果您遇到问题，我会建议您首先将

@PUT

更改为

@GET

，并删除

@消费（“应用程序/json”）

。通过浏览器浏览到此url（代码中有断点），并查看它是否到达。如果是这样，您可以返回到

@PUT

和

application/json

hi-Avi，我仍然会收到在处理请求期间发生的相同错误异常：与上下文路径[/appanalytix web]关联的命名空间[/]和操作名称[restServices/requirementservice/saverequirements]没有映射任何操作
