Step 2 : lombok Step 3 : Screenshot Step 4 : So how to use it
During the development of the project , There will be a lot of pojo. pojo Also called javabean,bean,entity wait , It's all him .
pojo There will be a lot of setter and getter , toString, hashcode, equals wait Everyone pojo Write , Added attribute to write , Reduce the number of attributes to write , still ... Very troublesome .
public class Hero { private int id; private String name; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return "Hero [id=" + id + ", name=" + name + "]"; } public Hero(int id, String name) { super(); this.id = id; this.name = name; } @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + id; result = prime * result + ((name == null) ? 0 : name.hashCode()); return result; } @Override public boolean equals(Object obj) { if (this == obj) return true; if (obj == null) return false; if (getClass() != obj.getClass()) return false; Hero other = (Hero) obj; if (id != other.id) return false; if (name == null) { if (other.name != null) return false; } else if (!name.equals(other.name)) return false; return true; } }
To be lazy , We can use lombok. After you use it, you will see the following code , Just add notes
import lombok.AllArgsConstructor; import lombok.Data; import lombok.EqualsAndHashCode; import lombok.NoArgsConstructor; import lombok.ToString; @Data public class Hero { private int id; private String name; }
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.NoArgsConstructor;
import lombok.ToString;
@Data
public class Hero {
private int id;
private String name;
}
To prove that I didn't write setter ,getter Can also access , Made a screenshot , You can see IDE The existing methods will pop up automatically , Promise , setter, getter, toString Something , It's all there -_-
In order to use , You need to install plug-ins to ... Next, we will explain how to eclipse and idea Use in .
