Spring MVC and AJAX with JSON
1. maven 配置
<!-- Spring Json -->
<dependency>
<groupId>net.sf.spring-json</groupId>
<artifactId>spring-json</artifactId>
<version>1.3.1</version>
<exclusions>
<exclusion>
<artifactId>sojo-optional</artifactId>
<groupId>net.sf.sojo</groupId>
</exclusion>
<exclusion>
<artifactId>spring-mock</artifactId>
<groupId>org.springframework</groupId>
</exclusion>
<exclusion>
<artifactId>spring</artifactId>
<groupId>org.springframework</groupId>
</exclusion>
<exclusion>
<artifactId>servlet-api</artifactId>
<groupId>javax.servlet</groupId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>net.sf.sojo</groupId>
<artifactId>sojo</artifactId>
<version>1.0.5</version>
<exclusions>
<exclusion>
<artifactId>commons-attributes-api</artifactId>
<groupId>commons-attributes</groupId>
</exclusion>
</exclusions>
</dependency>
2. 我们要在WEB-INF下面添加views.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation= "http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-2.5.xsd">
<bean name="jsonView" class="net.sf.json.spring.web.servlet.view.JsonView" />
</beans>
<!-- json -->
<bean id="xmlFileViewResolver" class="org.springframework.web.servlet.view.XmlViewResolver">
<property name="location">
<value>/WEB-INF/views.xml</value>
</property>
<property name="order">
<value>1</value>
</property>
</bean>
3.在ModelAndView 的后面，我们只要添加
return new ModelAndView("jsonView", modelMap);
就好了
提供一个简单的Sample
public ModelAndView getColumnsJson(HttpServletRequest request,
HttpServletResponse response) throws Exception {
Map<String,Object> modelMap = new HashMap<String,Object>(2);
modelMap.put("rows", service.generateColumns());
return new ModelAndView("jsonView", modelMap);
}
