java gson的使用

1、依赖jar包

gson-2.7.jar

2、调用方法：

Gson gson = new Gson();

String json = gson.toJson(user,UserEntity.class);

UserEntity user = new UserEntity();

user.setId(10);

user.setName("蔡晨力");

public class UserEntity {

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;

}

}
