链式编程
1 package com.nd.pdca.model; 2 3 public class Manager { 4 5 private String id; 6 private String userId; 7 private String userNo; 8 private String userName; 9 private String unitId; 10 11 public String getUserNo() { 12 return userNo; 13 } 14 15 public void setUserNo(String userNo) { 16 this.userNo = userNo; 17 } 18 19 public String getId() { 20 return id; 21 } 22 23 public void setId(String id) { 24 this.id = id; 25 } 26 27 public String getUnitId() { 28 return unitId; 29 } 30 31 public void setUnitId(String unitId) { 32 this.unitId = unitId; 33 } 34 35 public String getUserId() { 36 return userId; 37 } 38 39 public void setUserId(String userId) { 40 this.userId = userId; 41 } 42 43 public String getUserName() { 44 return userName; 45 } 46 47 public void setUserName(String userName) { 48 this.userName = userName; 49 } 50 51 public static Builder create() { 52 return new Builder(); 53 } 54 55 public static class Builder{ 56 private String id; 57 private String userId; 58 private String userNo; 59 private String userName; 60 private String unitId; 61 62 public Builder id(String id){ 63 this.id = id; 64 return this; 65 } 66 67 public Builder userId(String userId){ 68 this.userId = userId; 69 return this; 70 } 71 72 public Builder userNo(String userNo){ 73 this.userNo = userNo; 74 return this; 75 } 76 77 public Builder userName(String userName){ 78 this.userName = userName; 79 return this; 80 } 81 82 public Builder unitId(String unitId){ 83 this.unitId = unitId; 84 return this; 85 } 86 87 public Manager build(){ 88 Manager manager = new Manager(); 89 manager.setId(id); 90 manager.setUserName(userName); 91 manager.setUserId(userId); 92 manager.setUserNo(userNo); 93 manager.setUnitId(unitId); 94 return manager; 95 } 96 } 97 }
1 Manager manager = Manager.create().id(id).username(username).userId(userId).userNo(userNo).unitId(unitId).build(); 2 3 // 这样的链式编程就不需要调用set/get方法的形式了,使得在new的地方代码更为简洁好看。
构造Map
1 public class ParamBuilder { 2 3 private Map<String, Object> param = new HashMap<>(5); 4 5 public ParamBuilder withParam(String paramName, Object paramValue) { 6 param.put(paramName, paramValue); 7 return this; 8 } 9 10 public Map<String, Object> build() { 11 return param; 12 } 13 }
