Spring MVC使用@ResponseBody注解时返回中文出现乱码的解决办法

指定响应的字符集为utf-8，将@RequestMapping注解的produces属性的值设置为{"text/plain;charset=utf-8", "text/html;charset=utf-8"}

@ResponseBody
@RequestMapping(value = "/test", produces = {"text/plain;charset=utf-8", "text/html;charset=utf-8"})
public String test() {
    Student student = new Student();
    student.setName("11");
    student.setAge(10);
    studentService.add(student);
    return "添加成功";
}
