**测试 ToStringBuilder.reflectionToString() 和 toString() 打印字段属性过滤方法**

**1.实体类**

import lombok.Getter;
    import lombok.Setter;
    import lombok.ToString;
    
    import java.io.Serializable;
    
    /**
     * Created by BF100 on 2018/4/16.
     */
    @Setter
    @Getter
    @ToString(exclude = {"operatorIdNumber","id"})
    
    public class ResDto implements Serializable{
        private static final long serialVersionUID = 543897254415045735L;
        private String operatorIdNumber;
        private String id;
    
        public String getOperatorIdNumber() {
            return operatorIdNumber;
        }
    
        public void setOperatorIdNumber(String operatorIdNumber) {
            this.operatorIdNumber = operatorIdNumber;
        }
    
    }

2.ToStringBuilder.reflectionToString()和 **toString() 的打印结果展示**

@Test
        public void test2(){
            ResDto res = new ResDto();
            res.setId("123");
            res.setOperatorIdNumber("420624197708249914");
            // 脱敏身份证号
            res.setOperatorIdNumber(DataDesensUtil.dealSensIdCardNo(res.getOperatorIdNumber()));
    //        ReflectionToStringBuilder.toStringExclude(res, "operatorIdNumber");
            log.info("ToStringBuilder.reflectionToString :" + ToStringBuilder.reflectionToString(res));
            log.info("ToStringBuilderUtil.toString :" + ToStringBuilderUtil.toString(res));
            log.info("object.toString():" + res.toString());
        }

**3.ToStringBuilder.reflectionToString()  通过重写 ReflectionToStringBuilder 子类 , 覆盖其 accept 方法来加以筛选，其中toString 会会跳过名为operatorIdNumber 和 id 属性**

import org.apache.commons.lang.builder.ReflectionToStringBuilder;
    
    import java.lang.reflect.Field;
    
    /**
     * Created by BF100 on 2018/4/16.
     */
    public class ToStringBuilderUtil  {
    
        public static String toString(Object o) {
    
            return (new ReflectionToStringBuilder(o) {
    
                protected boolean accept(Field f) {
                    return super.accept(f) && !f.getName().equals("operatorIdNumber") && !f.getName().equals("id");
    
                }}).toString();
        }
    }

log.info("ToStringBuilderUtil.toString :" + ToStringBuilderUtil.toString(res));

就会打印出 res 的 属性 不包含 id 和 operatorIdNumber
