解决Java Web应用中的乱码问题-优快云博客

乱码问题解决

客户端（360浏览器编码设置）

代码演示

form.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<form action="/tian/e/t1" method="post">
    <input type="text" name="name">
    <input type="submit">
</form>
</body>
</html>

EncodingController

@Controller
public class EncodingController {
    //过滤器解决乱码
    @PostMapping("/e/t1")
    public String test1(String name,Model model){

        model.addAttribute("msg",name);
        return "test";
    }
}

测试发现乱码

发现过滤器和设置编码都不行

解决方法

在webxml配置(也是固定的死代码)

<!--配置springmvc的乱码过滤-->
<filter>
    <filter-name>encoding</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>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
