MyBatisPlus的ActiveRecord实现CRUD

实现

Model中的方法

测试ARInsert

/***
  * 测试 AR insert
  */
 @Test
 public void testARInsert() {
  
  Employee employee = new Employee();
  employee.setName("ARinsert测试");
  employee.setAge(23);
  Boolean result = employee.insert();
  System.out.println("************************"+result);
  Integer id = employee.getId();
  System.out.println("*********************"+id);
 }

运行结果

测试ARUpdate

/***
  * AR更新操作
  */
 @Test
 public void testARUpdate() {
  
  Employee employee = new Employee();
  employee.setId(14);
  employee.setName("AR更新测试成功");
  boolean result=employee.updateById();
  System.out.println("*******************"+result);
 }

运行结果

测试ARSelectById

/***
  * AR  通过ID查询
  */
 @Test
 public void testARSelectById() {
  
  Employee employee=new Employee();
  employee.setId(14);
  Employee result = (Employee) employee.selectById();
  System.out.println("*******************"+result.getName());
 }

运行结果

测试ARSelectAll

/***
  * AR  selectAll
  */
 @Test
 public void testARSelectAll() {
  
  Employee employee=new Employee();
  
  List<Model> list  = employee.selectAll();
  
  for (Model model : list) {
   System.out.println("*******************"+((Employee) model).getName());
  }
  
 }

运行结果

测试ARSelectList

/***
  * AR  selectList
  */
 @Test
 public void testARSelectList() {
  
  Employee employee=new Employee();
  
  List<Model> list =employee.selectList(new EntityWrapper<Employee>().like("name", "霸"));
  
  for (Model model : list) {
   System.out.println("*******************"+((Employee) model).getName());
  }
  
 }

运行结果

测试ARDeleteById

/***
  * AR  DeleteByID
  */
 @Test
 public void testARDeleteByID() {
  
  Employee employee=new Employee();
  employee.setId(14);
  Boolean result = employee.deleteById();
  System.out.println("*******************"+result);
  
 }

运行结果

测试ARDelete

/***
  * AR  Delete  删除不存在的数据在逻辑上也是成功的
  */
 @Test
 public void testARDelete() {
  
  Employee employee=new Employee();
  Boolean result = employee.delete(new EntityWrapper<Employee>().eq("id", "14"));
  System.out.println("*******************"+result);
  
 }

运行结果

测试ARSelectPage

/***
  * AR  分页
  */
 @Test
 public void testARPage() {
  
  Employee employee=new Employee();
  Page<Model> page = employee.selectPage(new Page<Model>(1,2), new EntityWrapper<Model>().like("name", "霸"));
  List<Model> list =page.getRecords();
  for (Model model : list) {
   System.out.println("*******************"+model);
  }
  
  
 }

运行结果
