spring - 使用 Spring 在 CXF 中配置多个 resouceBean

Question

我正在使用带有 Spring 3.0.6-RELEASE 的 CXF RS 2.5.1。我想为“单个端点”提供多个实现类。我看到有人报告并修复了这个问题 https://issues.apache.org/jira/browse/CXF-2439但是，当我尝试这样做时，CXF 只是从 jaxrs:serviceBeans 标记中选择第一个资源类。对于另一个请求，我在 tomcat 控制台上看到此消息为“找不到匹配请求路径/account/rest/transfer 的操作”。下面是配置。感谢任何输入。

web.xml

    <listener>
        <listener-class> org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:account-servlet.xml</param-value>
    </context-param>

      <servlet>
    <servlet-name>CXF Servlet</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
       </servlet>

      <servlet-mapping>
    <servlet-name>CXF Servlet</servlet-name>
    <url-pattern>/*</url-pattern>
      </servlet-mapping>

account-servlet.xml

    <jaxrs:server id="accountService" address="/rest">
        <jaxrs:serviceBeans>
            <ref bean="transferService" />
                <ref bean="balanceService"/>
        </jaxrs:serviceBeans>
        <jaxrs:extensionMappings>
            <entry key="xml" value="application/xml" />
        </jaxrs:extensionMappings>
    </jaxrs:server>


    <bean id="transferService" class="com.mycompany.service.TransferService"/>
    <bean id="balanceService" class="com.mycompany.service.BalanceService"/>

BalanceService.java(省略导入)

        package com.mycompany.service;
        @Path("/")
         @Produces("application/xml")
        public class BalanceService{

    @GET
    @Path("/balance")
    public String getBalance() {
        StringBuilder response = new StringBuilder(128);
        response.append("<Balance>")
            .append("<amount>").append("250.00").append("</amount>")
            .append("</Balance>");
        return response.toString();
    }
       }

TransferService.java(省略导入)

package com.mycompany.service;

@Path("/")
@Produces("application/xml")
public class TransferService {

    @GET
    @Path("/transfer")
    public String getTransfer() {

        StringBuilder response = new StringBuilder(128);
        response.append("<Transfer>")
            .append("<amount>").append("350.00").append("</amount>")
            .append("</Transfer>");
        return response.toString();
    }
  }

请忽略任何编程违规/标准，因为它只是 POC 的示例应用程序。

我通过将 @Path 映射的一部分移动到服务 bean 类来解决这个问题。在你的情况下:

BalanceService

@Path("/balance")
@Produces("application/xml")
public class BalanceService {
    @GET
    @Path("/{id}")
    public String getBalance(@PathParam("id") long id) {
        ...
    }
}

TransferService

@Path("/transfer")
@Produces("application/xml")
public class TransferService {

    @GET
    @Path("/{id}")
    public String getTransfer(@PathParam("id") long id) {
       ...      
    }
}
