Validation framework usage example

• Sample code:

  @Validation(mode = Validation.MODE.FULL)
  public class UserBase {
  
      @VRequried(msg = "{0}不能为空")
      @VLength(min = 3, max = 16, msg = "{0}长度必须在3到16之间")
      @VField(label = "用户名称")
      private String username;
  
      @VRequried
      @VLength(max = 32)
      private String password;
  
      @VRequried
      @VCompare(cond = VCompare.Cond.EQ, with = "password")
      private String repassword;
  
      @VModel
      @VField(name = "ext")
      private UserExt userExt;
  
      //
      // 此处省略了Get/Set方法
      //
  }
  
  public class UserExt {
  
      @VLength(max = 10)
      private String sex;
  
      @VRequried
      @VNumeric(min = 18, max = 30)
      private int age;
  
      @VRequried
      @VEmail
      private String email;
  
      //
      // 此处省略了Get/Set方法
      //
  }
  
  public static void main(String[] args) throws Exception {
      YMP.get().init();
      try {
          Map<String, Object> _params = new HashMap<String, Object>();
          _params.put("username", "lz");
          _params.put("password", 1233);
          _params.put("repassword", "12333");
          _params.put("ext.age", "17");
          _params.put("ext.email", "@163.com");
  
          Map<String, ValidateResult> _results = Validations.get().validate(UserBase.class, _params);
          //
          for (Map.Entry<String, ValidateResult> _entry : _results.entrySet()) {
              System.out.println(_entry.getValue().getMsg());
          }
      } finally {
          YMP.get().destroy();
      }
  }

• Execution result:

  username : 用户名称长度必须在3到16之间
  repassword : repassword must be eq password.
  ext.age : ext.age numeric must be between 30 and 18.
  ext.email : ext.email not a valid email address.

Function annotation description:

• @Validation: Verification mode configuration, The default is NORMAL;

  • NORMAL - short-circuit verification, that is, if the verification fails, the verification result will be returned;
  • FULL - all verification results will be returned after all verification of the target object attributes;

• @VField: Customize the member or method parameter name to be verified;

  • name: Customize the parameter name , the upper and lower parameters are separated by '.' during nested verification;
  • label: Custom parameter label name, if @VField is used nested, the function will not be available;

• @VModel: Declare whether the target object is a JavaBean object, and object nested verification will be performed;
