Question

我正在使用servlet3和jsp处理j2EE项目，并使用restful服务提供应用程序数据。所以我使用以下依赖项来获取我的pom.xml中的restful服务

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>
    <version>2.2.1.GA</version>
</dependency>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jackson-provider</artifactId>
    <version>2.2.1.GA</version>
</dependency>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxb-provider</artifactId>
    <version>2.2.0.GA</version>
</dependency>

这里，我有一个名为MyServices的类文件，它有以下代码，这样就无需在web.xml文件中编写代码来启动restful servlet。

@ApplicationPath("f")
public class MyServices extends Application {
    private Set<Object> singletons = new HashSet<Object>();

    public MyServices() {
        singletons.add(new MyAppServices());
        singletons.add(new MyCommonServices());
        singletons.add(new MyAddonServices());
    }

    @Override
    public Set<Object> getSingletons() {
        return singletons;
    }
}

下面，粘贴了在MyServices.Java中启动的所有3个类。

MyAppServices.Java的路径为/ mobapi，可以通过localhost:8080/myapp/mobapi/..访问

@Path(value = "/mobapi")
public class MyAppServices {

    @GET
    @Path(value = "/app/{param}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response getMsg(@PathParam(value = "param") String appId) {
        String token = documentDAO.mobileAppToken(appId);
        return Response.status(200).entity(token).build();
    }
}

MyCommonServices.Java的路径为/，这意味着什么，可以通过localhost:8080/myapp/..访问

@Path(value = "/")
public class MyCommonServices {

    @GET
    @Path(value = "/app/{param}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response getMsg(@PathParam(value = "param") String appId) {
        String token = documentDAO.mobileAppToken(appId);
        return Response.status(200).entity(token).build();
    }
}

MyAddonServices.Java的路径为/ api，可以通过localhost:8080/myapp/api/..访问

@Path(value = "/api")
public class MyAddonServices {

    @GET
    @Path(value = "/app/{param}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response getMsg(@PathParam(value = "param") String appId) {
        String token = documentDAO.mobileAppToken(appId);
        return Response.status(200).entity(token).build();
    }
}

问题是我只能localhost:8080/myapp/app/6546无问题地访问。

但是，我无法访问其他API，例如localhost:8080/myapp/api/app/6546或localhost:8080/myapp/mobapi/app/6546

这里是否还有其他任何配置，请问有人帮忙吗？

我使用过滤器来处理像localhost:8080/myApp/app/something到localhost:8080/myApp/f/app/something之类的地图请求，如下所示

MyFilter.java

@WebFilter(urlPatterns = "/*")
public class MyFilter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        if (request instanceof HttpServletRequest) {
            String path = ((HttpServletRequest) request).getServletPath();
            boolean isGet = "GET".equals(((HttpServletRequest) request)
                    .getMethod());
            String newPath = null;
            ((HttpServletRequest) request).getQueryString();

            try {
                ((HttpServletRequest) request).getQueryString();
                if (path.contains("api/")) {
                    newPath = "f"
                            + path
                            + "?"
                            + ((HttpServletRequest) request)
                                    .getQueryString();
                }else {
                    newPath = "f"
                            + path
                            + "?"
                            + ((HttpServletRequest) request)
                                    .getQueryString();
                }
            } catch (Exception e) {
                newPath = "f" + path;

            }
            request.getRequestDispatcher(newPath).forward(request, response);
            return;
        }
        chain.doFilter(request, response);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void destroy() {
    }
}

如果我删除此过滤器，我可以访问所有api，而不会出现localhost:8080/myApp/f/app/something＆amp;本地主机：8080 /对myApp / F / API /应用/东西&localhost:8080/myApp/f/mobapi/app/something

有人可以帮助这个过滤器吗？

尝试这样做：

MyCommonServices.Java

@Path(value = "/app/{param}")
public class MyCommonServices {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Response getMsg(@PathParam(value = "param") String appId) {
        String token = documentDAO.mobileAppToken(appId);
        return Response.status(200).entity(token).build();
    }
}

MyAppServices.Java

@Path(value = "/mobapi/app/{param}")
public class MyAppServices {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Response getMsg(@PathParam(value = "param") String appId) {
        String token = documentDAO.mobileAppToken(appId);
        return Response.status(200).entity(token).build();
    }
}

MyAddonServices.Java

@Path(value = "/api/app/{param}")
public class MyAddonServices {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Response getMsg(@PathParam(value = "param") String appId) {
        String token = documentDAO.mobileAppToken(appId);
        return Response.status(200).entity(token).build();
    }
}

Answer 2

如果您将MyCommonServices从@Path(value = "/")更改为@Path(value = "/app")和@Path(value = "/app/{param}")更改为@Path(value = "/{param}")，该怎么办？

J2EE中的Restful服务配置不起作用
