Java通过反射获取枚举中的值

enum StudentEnum {
    ZS("LINS1","zs", "18"),
    LS("LINS2","ls", "16"),
    WW("LINS3","ww", "16");
    private String lable;
    private String name;
    private String age;
    public String getLable() {
        return lable;
    }
    public void setLable(String lable) {
        this.lable = lable;
    }
    StudentEnum(String lable, String name, String age) {
        this.name = name;
        this.lable = lable;
        this.age = age;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getAge() {
        return age;
    }
    public void setAge(String age) {
        this.age = age;
    }
    public static StudentEnum getByName(String name) {
        StudentEnum[] values = StudentEnum.values();
        for (StudentEnum studentEnum : values) {
            if (StringUtils.equals(name, studentEnum.getName())) {
                return studentEnum;
            }
        }
        return null;
    }
}

• Student对象 ```java @Data public class Student {

  private String age; private String name;

}

反射获取
```java
@org.junit.Test
public void test5() throws Exception {
    Student stu = new Student();
    //模拟解析json后的lable的值
    String inputLable = "LINS2";
    Class<StudentEnum> testEnumClass = StudentEnum.class;
    StudentEnum[] enumConstants = testEnumClass.getEnumConstants();
    Method getLable = testEnumClass.getMethod("getLable");
    Method getName = testEnumClass.getMethod("getName");
    Method getAge = testEnumClass.getMethod("getAge");
    for (StudentEnum studentEnum : enumConstants) {
        if (StringUtils.equals(inputLable,getLable.invoke(studentEnum).toString())){
            stu.setAge(getAge.invoke(studentEnum).toString());
            stu.setName(getName.invoke(studentEnum).toString());
        }
    }
    System.out.println(stu);
}

运行结果
