使用jersey搭建的restful接口，不一定是最优方案。

springMVC 可能才是最完美的解决方案。

1.配置maven，加载jersey相关的jar包

<dependency>
    			<groupId>com.sun.jersey</groupId>
    			<artifactId>jersey-server</artifactId>
    			<version>1.9</version>
    		</dependency>
    		<dependency>
    			<groupId>com.sun.jersey</groupId>
    			<artifactId>jersey-json</artifactId>
    			<version>1.9</version>
    		</dependency>
    		<dependency>
    			<groupId>com.sun.jersey</groupId>
    			<artifactId>jersey-client</artifactId>
    			<version>1.9</version>
    		</dependency>
    		<dependency>
    			<groupId>com.sun.jersey</groupId>
    			<artifactId>jersey-fastinfoset</artifactId>
    			<version>1.9</version>
    		</dependency>
    		<dependency>
    			<groupId>com.sun.jersey.contribs</groupId>
    			<artifactId>jersey-spring</artifactId>
    			<version>1.9</version>
    			
    			<exclusions>
    				<exclusion>
    					<groupId>org.springframework</groupId>
    					<artifactId>spring-aop</artifactId>
    				</exclusion>
    				<exclusion>
    					<groupId>org.springframework</groupId>
    					<artifactId>spring-context</artifactId>
    				</exclusion>
    				<exclusion>
    					<groupId>org.springframework</groupId>
    					<artifactId>spring-beans</artifactId>
    				</exclusion>
    				<exclusion>
    					<groupId>org.springframework</groupId>
    					<artifactId>spring-core</artifactId>
    				</exclusion>
    				<exclusion>
    					<artifactId>spring-web</artifactId>
    					<groupId>org.springframework</groupId>
    				</exclusion>
    			</exclusions>
    		</dependency>

2.配置web.xml文件

<servlet>
    		<servlet-name>JerseyServlet</servlet-name>
    		<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
    	</servlet>
    	<servlet-mapping>
    		<servlet-name>JerseyServlet</servlet-name>
    		<url-pattern>/REST/*</url-pattern>
    	</servlet-mapping>

3.编写接口API

import javax.servlet.http.HttpServletRequest;
    import javax.ws.rs.POST;
    import javax.ws.rs.Path;
    import javax.ws.rs.Produces;
    import javax.ws.rs.core.Context;
    import javax.ws.rs.core.MediaType;
    
    import net.sf.json.JSONObject;
    
    import org.apache.commons.logging.Log;
    import org.apache.commons.logging.LogFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Component;
    
    import com.sand.mag.bean.QSRentaResultInBean;
    import com.sand.mag.bean.QSRentalInBean;
    import com.sand.mag.bean.QSRentalOutBean;
    import com.sand.mag.common.MAGConstant;
    import com.sand.mag.operation.QSRentalOperation;
    import com.sand.mag.operation.QSRentalResultOperation;
    import com.sand.mag.operation.base.OPCaller;
    import com.sand.mag.operation.base.OperationContext;
    import com.sand.mag.utils.StrUtil;
    
    @Component
    @Path("/QSRentalAPI")
    public class QsRentalAPI {
    
    	private final static Log logger = LogFactory.getLog(QsRentalAPI.class);
    	@Autowired
    	private OperationContext context;
    
    	@Path("QSRental")
    	@Produces({ MediaType.TEXT_PLAIN })
    	@POST
    	public String qsRental(@Context HttpServletRequest request) {
    		String response = "";
    		try {
    			String json = StrUtil.buildJsonString(request);
    			QSRentalInBean bean = (QSRentalInBean) JSONObject.toBean(
    					JSONObject.fromObject(json), QSRentalInBean.class);
    			context.setAttribute(QSRentalOperation.IN_BEAN, bean);
    			OPCaller.call(QSRentalOperation.ID, context);
    			response = (String) context
    					.getAttribute(QSRentalOperation.OUT_STRING);
    		} catch (Exception e) {
    			e.printStackTrace();
    			if (e.getMessage().equals(MAGConstant.C_CHECK_SIGN_FAIL)) {
    				return QSRentalOutBean.jsonCommonReturn(MAGConstant.C_CHECK_SIGN_FAIL,
    						MAGConstant.M_CHECK_SIGN_FAIL);
    			}
    			if (e.getMessage().equals(MAGConstant.C_SYSTEM_EXCEPTION)) {
    				return QSRentalOutBean.jsonCommonReturn(MAGConstant.C_SYSTEM_EXCEPTION,
    						MAGConstant.M_SYSTEM_EXCEPTION);
    			}
    			return QSRentalOutBean.jsonCommonReturn(MAGConstant.C_FAIL,
    					MAGConstant.M_FAIL);
    		}
    		logger.info("返回数据  : " + response);
    		return response;
    	}
    
    	@Path("QSRentalSendResult")
    	@Produces({ MediaType.TEXT_PLAIN })
    	@POST
    	public String qsRentalSendResult(@Context HttpServletRequest request) {
    		String response = "";
    		try {
    			QSRentaResultInBean bean = new QSRentaResultInBean(request);
    			context.setAttribute(QSRentalResultOperation.IN_BEAN, bean);
    			OPCaller.call(QSRentalResultOperation.ID, context);
    			response = (String) context
    					.getAttribute(QSRentalResultOperation.OUT_STRING);
    		} catch (Exception e) {
    			e.printStackTrace();
    			if (e.getMessage().equals(MAGConstant.C_SYSTEM_EXCEPTION)) {
    				return QSRentalOutBean.jsonCommonReturn(MAGConstant.C_SYSTEM_EXCEPTION,
    						MAGConstant.M_SYSTEM_EXCEPTION);
    			}
    			return QSRentalOutBean.jsonCommonReturn(MAGConstant.C_FAIL,
    					MAGConstant.M_FAIL);
    		}
    		logger.info("返回数据  : " + response);
    		return response;
    	}
    
    }

4.测试

火狐浏览器有插件：HttpRequester方便测试

测试地址：

慢慢调试吧
