JAX-RS 和 和 Spring 整合开发

1、建立maven项目

2、导入maven坐标

<dependencies>
          <!-- cxf 进行rs开发 必须导入  -->
          <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxrs</artifactId>
            <version>3.0.1</version>
        </dependency>

        <!-- 日志引入  -->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.12</version>
        </dependency>

        <!-- 客户端 -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-rs-client</artifactId>
            <version>3.0.1</version>
        </dependency>

        <!-- 扩展json提供者 -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-rs-extension-providers</artifactId>
            <version>3.0.1</version>
        </dependency>
    
        <!-- 转换json工具包，被extension providers 依赖 -->
        <dependency>
            <groupId>org.codehaus.jettison</groupId>
            <artifactId>jettison</artifactId>
            <version>1.3.7</version>
        </dependency>
        
        <!-- spring 核心 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>4.1.7.RELEASE</version>
        </dependency>

        <!-- spring web集成 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>4.1.7.RELEASE</version>
        </dependency>
    
        <!-- spring 整合junit  -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>4.1.7.RELEASE</version>
        </dependency>

        <!-- junit 开发包 -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
  </dependencies>

3、配置web.xml

<!-- spring配置文件位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- spring核心监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    
    <servlet>
        <servlet-name>CXFService</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>CXFService</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>

4、编写实体类与Service

5、在applicationContext.xml中配置发布RS服务

 

<!-- 
        address 发布服务地址 
        servicesBeans 服务实现类 
     -->
    <jaxrs:server id="userService" address="/userService" >
        <jaxrs:serviceBeans>
            <bean class="cn.itcast.cxf.service.UserServiceImpl" />
        </jaxrs:serviceBeans>
        <jaxrs:inInterceptors>
            <bean class="org.apache.cxf.interceptor.LoggingInInterceptor" />
        </jaxrs:inInterceptors>
        <jaxrs:outInterceptors>
            <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor" />
        </jaxrs:outInterceptors>
    </jaxrs:server>

6、配置服务启动端口

<build>
      <plugins>
          <plugin>
              <groupId>org.codehaus.mojo</groupId>
              <artifactId>tomcat-maven-plugin</artifactId>
              <version>1.1</version>
              <configuration>
                  <port>9996</port>
              </configuration>
          </plugin>
      </plugins>
  </build>
