Spring3.0+JsonView/Jackson

  一、web.xml 配置：

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app><display-name>Archetype Created Web Application</display-name>         <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>    classpath*:spring/*.xml    </param-value>    </context-param>     <!-- Filter encoding --><filter><filter-name>CharacterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter>     <filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>    <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>     <servlet><servlet-name>spring</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath*:spring/spring-p2p-console.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>spring</servlet-name><url-pattern>*.con</url-pattern></servlet-mapping></web-app>

二、spring-servlet.xml 配置

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="        http://www.springframework.org/schema/beans             http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-3.0.xsd        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">          <context:annotation-config /><tx:annotation-driven transaction-manager="transactionManager"/><context:component-scan base-package="com.icardpay.business.p2p.console.controller" /> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"destroy-method="close"><property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" /><property name="url" value="jdbc:oracle:thin:@192.168.1.8:1521:ORCL" /><property name="username" value="root" /><property name="password" value="root" /></bean><bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="locations">            <list>                <value>classpath:project.properties</value>            </list>        </property>    </bean>     <!--     <bean class="org.springframework.web.servlet.view.BeanNameViewResolver">        <property name="order" value="1"/>    </bean>        <bean name="jsonView" class="org.springframework.web.servlet.view.json.JsonView"><property name="jsonWriter"><ref bean="jsonWriter" /></property></bean><bean name="jsonWriter" class="org.springframework.web.servlet.view.json.writer.sojo.SojoJsonStringWriter"><property name="convertAllMapValues"><value>true</value></property></bean>  -->//注释掉为JsonView<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">              <property name="messageConverters">                  <list >                      <ref bean="mappingJacksonHttpMessageConverter" />                  </list>              </property>          </bean>     <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">        <property name="supportedMediaTypes">            <list>                <value>application/json;charset=UTF-8</value>           </list>        </property>  </bean>      </beans>

三、pom.xml

<!-- json --><dependency><groupId>org.codehaus.jackson</groupId><artifactId>jackson-core-lgpl</artifactId></dependency><dependency><groupId>org.codehaus.jackson</groupId><artifactId>jackson-mapper-lgpl</artifactId></dependency>

四、Controller代码

@Controller@RequestMapping("/xxx")public class aaaaaController {private static Logger logger = LoggerFactory.getLogger(aaaaaController.class);@Resourceprivate ffffBiz xxxxeeee;    @RequestMapping("/test_json")    @ResponseBody      public Map<String,Object>  testJson3(Param p){    System.out.println("enter....");    System.out.println("value....=========="+p.getId());     Map<String,Object> map = new HashMap<String,Object>();           map.put("code", true);      return map;    }}
