反射加注解获取实体bean属性和注解值

--注解Annotation
import java.lang.annotation.*;

import static java.lang.annotation.RetentionPolicy.RUNTIME;

@Documented
@Inherited
@Target(ElementType.FIELD)
@Retention(RUNTIME)
public @interface Attribute {

    String name() default "";

}

实体bean用法

 

调用方法，获取所有属性和注解的值

 

package com.sic.credit.collection;

import com.sic.credit.api.datacollection.bo.common.ResourceCatalogBo;
import com.sic.credit.api.datacollection.util.Attribute;

import java.lang.reflect.Field;
import java.util.*;

public class test {

    public static void main(String[] args) throws Exception{
        List headerName = new ArrayList();
        List headerKey = new ArrayList();
        //得到class
        Class clazz = ResourceCatalogBo.class;
        //得到所有属性
        Field[] fields = clazz.getDeclaredFields();
        List list = new ArrayList<>();
        list.addAll(Arrays.asList(fields));
        Class superClazz = clazz.getSuperclass();
        if (superClazz != null) {
            Field[] superFields = superClazz.getDeclaredFields();
            for (int i=0;i

 

输出结果为
