javaee SpringMVC 乱码问题解决

方法一

在web.xml文件中注册过滤器

<!-- 注册过滤器  设置编码 --><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><init-param><param-name>forceResponseEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>

方法二

在注解中添加编码设置，主要是处理ajax请求乱码
produces = “text/html;charset=utf-8”

 @RequestMapping(value="/getMajorList2",produces = "text/html;charset=utf-8")@ResponseBodypublic String getMajorList2(){List<Major> majorList=new ArrayList<Major>();majorList.add(new Major(1,"计算机"));majorList.add(new Major(2,"英语"));return JSON.toJSONString(majorList);}

方法三

修改tomcat的sever.xml文件
添加 URIEncoding=“utf-8”
主要解决post请求乱码

 <Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="utf-8" />
