1.添加jakson包支持
<!-- jakson版本号 --> <jackson.version>2.7.9</jackson.version> <!-- jackson --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>${jackson.version}</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>${jackson.version}</version> </dependency>
2.springmvc.xml中配置bean
<!-- 用于将对象转化为JSON --> <bean id="stringConverter" class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/plain;cahrtset=utf-8</value> </list> </property> </bean> <bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" /> <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="stringConverter"/> <ref bean="jsonConverter"/> </list> </property> </bean>
3.User.java
public class User {
private int id;
private String name;
private String sex;
public User() {
}
public User(int id, String name, String sex) {
super();
this.id = id;
this.name = name;
this.sex = sex;
}
//get/set方法省略
}
4.Controller.java
@Controller public class JsonController { @RequestMapping("/json") //指示方法返回值的注释应绑定到Web响应正文。即将返回值直接传到页面（xhr类型） @ResponseBody public List<User> json(){ List<User> list = new ArrayList<User>(); User u1 = new User(1, "丽娜", "女"); User u2 = new User(2, "刘杰", "男"); User u3 = new User(3, "徐斌", "男"); list.add(u1); list.add(u2); list.add(u3); // System.out.println(list); return list; } }
5.json.jsp页面
<script type="text/javascript" src="js/jquery.min.js"></script> <script type="text/javascript"> $(function(){ $("#btn").click(function(){ $.post("json.do",function(data){ //返回的是object对象 var html = ""; for(var i=0;i<data.length;i++){ //拼接表格 html+="<tr><td>"+data[i].id+"</td><td>"+data[i].name+"</td><td>"+data[i].sex+"</td></tr>"; } $("#tbody").html(html); }); }); }); </script> </head> <body> <button id="btn">显示数据</button><br> <hr> <table width="80%"> <tr> <td>编号:</td> <td>姓名:</td> <td>性别:</td> </tr> <tbody id="tbody"></tbody> </table> </body>
