使用ToStringBuilder重写toString方法，

使用ToStringBuilder重写toString方法，

1.定义实体：

package com.osc.demo;

import java.util.List;

import org.apache.commons.lang.builder.ToStringBuilder;
import org.apache.commons.lang.builder.ToStringStyle;

public class Teacher {
    private String name;
    private int age;
    private List<Student> student;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public List<Student> getStudent() {
        return student;
    }

    public void setStudent(List<Student> student) {
        this.student = student;
    }

    @Override
    public String toString() {
        //return new ToStringBuilder(this,ToStringStyle.SHORT_PREFIX_STYLE).append("name", this.name).append("age",this.age).append("student",this.student).toString();
        return ToStringBuilder.reflectionToString(this,ToStringStyle.SHORT_PREFIX_STYLE);
    }
}

package com.osc.demo;

import org.apache.commons.lang.builder.ToStringBuilder;
import org.apache.commons.lang.builder.ToStringStyle;

public class Student {
    private String name;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        //return new ToStringBuilder(this,ToStringStyle.SHORT_PREFIX_STYLE).append("name", this.name).append("age",this.age).toString();
        return ToStringBuilder.reflectionToString(this,ToStringStyle.SHORT_PREFIX_STYLE);
    }
}

2.测试

package com.osc.demo;

import java.util.ArrayList;
import java.util.List;

public class Test {
    public static void main(String[] args) {
        Student studentOne = new Student();
        studentOne.setName("学生");
        studentOne.setAge(34);
        List<Student> studentList = new ArrayList<Student>();
        studentList.add(studentOne);
        Teacher teacher = new Teacher();
        teacher.setName("老师");
        teacher.setAge(33);
        teacher.setStudent(studentList);
        System.out.println(teacher);
    }
}

输出结果：

Teacher[name=陈冠希,age=33,student=[Student[name=张柏芝,age=34]]]
