Java fluent风格
写个简单的例子,相信看了下面的例子,就会了解什么是fluent风格。
一.我们先写一个通常的,即不使用fluent风格
1.实体类
package com.xbq.demo.stu; /** * @ClassName: Student * @Description: TODO(学生实体类) * @author xbq * @date 2017-3-26 下午9:54:00 */ public class Student { private String name; private String address; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } @Override public String toString() { return "Student [name=" + name + ", address=" + address + "]"; } }
2.测试类
package com.xbq.demo.stu; /** * @ClassName: Test * @Description: TODO(测试学生实体,非 fluent风格) * @author xbq * @date 2017-3-26 下午9:55:34 */ public class Test { public static void main(String[] args) { Student student = new Student(); student.setName("张三"); student.setAddress("广东深圳"); System.out.println(student); } }
二.再写一个使用fluent风格的
1.实体类
package com.xbq.demo; /** * @ClassName: Student * @Description: TODO(学生实体类) * @author xbq * @date 2017-3-26 下午7:56:20 */ public class Student { private String name; private String address; // 设置name的值,并且返回实体 public Student setName(String name){ this.name = name; return this; } // 设置address的值,并且返回实体 public Student setAddress(String address){ this.address = address; return this; } public String getName() { return name; } public String getAddress() { return address; } // 返回学生实体,可以做成单例 public static Student build(){ return new Student(); } @Override public String toString() { return "Student [name=" + name + ", address=" + address + "]"; } }
2.测试类
package com.xbq.demo; /** * @ClassName: Test * @Description: TODO(测试学生实体, fluent风格) * @author xbq * @date 2017-3-26 下午9:59:22 */ public class Test { public static void main(String[] args) { Student student = Student.build().setName("李四").setAddress("广东广州"); System.out.println(student.getName()); } }
