[错误解决]SpringMVC接收对象 中文乱码问题解决

错误描述 ：

对于以下一段简单前端代码示例：

<!-- 请求对象实体类 -->
      <form action="SpringMVCHandler/testObjectProperties" method="post">
          学号：<input type="text" name="id"><br>
          姓名：<input type="text" name="name"><br>
          家庭住址：<input type="text" name="address.homeAddress"><br>
          学校地址：<input type="text" name="address.schoolAddress"><br>
          <input type="submit" value="实体类传参(便捷)">
      </form>

以及后台接收代码：

    @RequestMapping(value="testObjectProperties")
    public String testCookieValue(Student student) {//student 必须与form表单中的属性一致（支持级联属性）
        System.out.println(student.getId()+" "+student.getName()+" "+student.getAddress().getHomeAddress()+" "+student.getAddress().getSchoolAddress());
        return "success";
    }

以及两个实体类Student以及Address

Student.java

package org.zlc.entity;

public class Student {
    private int id;
    private String name;
    private Address address;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Address getAddress() {
        return address;
    }
    public void setAddress(Address address) {
        this.address = address;
    }
}

Address.java

package org.zlc.entity;

public class Address {
    private String homeAddress;
    private String SchoolAddress;
    public String getHomeAddress() {
        return homeAddress;
    }
    public void setHomeAddress(String homeAddress) {
        this.homeAddress = homeAddress;
    }
    public String getSchoolAddress() {
        return SchoolAddress;
    }
    public void setSchoolAddress(String schoolAddress) {
        SchoolAddress = schoolAddress;
    }
    
}

在前端输入后控制台会输出输入内容

 

但如果为中文则会输出乱码

 解决办法：

在web.xml添加字符集拦截器

    <!-- 字符集过滤器 -->
    <filter>
        <description>字符集过滤器</description>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <description>字符集编码</description>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>

    <!-- 字符集拦截 -->
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

中文不再乱码
