JSR303 Verification--hibernate-validator Implementation

This article is a Spring+springmvc+mybatis project, but the JSR303 checksum uses the implementation provided by Hibernate.

1. Join MAVEN

<!--JSR303 Data validation Support: TOMCAT7 and above Servers -  <Dependency>      <groupId>Org.hibernate</groupId>      <Artifactid>Hibernate-validator</Artifactid>      <version>5.4.1.Final</version>  </Dependency>  

2. Add a validation rule to the entity class to validate

 Public class Employee {      private  Integer empId;      @Pattern (RegExp= ("(^[a-za-z0-9_-]{6,16}$) | ( ^[\\u2e80-\\u9fff]{2,5}$), message= "User name must be legal")      private  String empname      ; Private String gender;      @Pattern (RegExp= ("^ ([a-z0-9_\\.-]+) @ ([\\da-z\\.-]+) \ \. [A-z\\.] {2,6}) $ "), message=" The mailbox format must be legal! " )      private  String email;       Private Integer did;  }  

3. Add the @valid annotation and the "Bindingresult result" method to receive the validation results and return the validation results to the front-end display.

/*** Employee Save * 1. Support JSR303 Check * 2. Import Hibernate-validator*/@RequestMapping (Value= "/emp", method=requestmethod.post) @ResponseBody PublicMsg saveemp (@Valid Employee employee,bindingresult result) {if(Result.haserrors ()) {//validation failed, return failed, display failed error message in modal boxlist<fielderror> errors =result.getfielderrors (); Map<string, object> map =NewHashmap<string, object>();  for(Fielderror fielderror:errors) {System.out.println ("Wrong field name:" +Fielderror.getfield ()); System.out.println ("Error message:" +fielderror.getdefaultmessage ());          Map.put (Fielderror.getfield (), Fielderror.getdefaultmessage ()); }          returnMsg.fail (). Add ("Errorfield", map); }Else{employeeservice.saveemp (employee); returnmsg.success (); }  }

4. Front-end display

//2. Save$.ajax ({URL:"${ctx}/emp", type:"POST", data:$ ("#empAddModal form"). Serialize (), Success:function(data) {if(data.code==100){              //1. Close the modal frame$ ("#empAddModal"). Modal ("Hide"); //2. Come to the last pageTo_page (9999); }Else{              //Display failure Information            //Which field is displayed with the error message of the field            if(Undefined! =data.extend.errorField.email) {                  //Display mailbox error messagesShow_validate_msg ("#email_add_input", "Error", Data.extend.errorField.email); }              if(Undefined! =data.extend.errorField.empName) {Show_validate_msg ("#empName_add_input", "Error", Data.extend.errorField.empName); }}}, error:function(data) {}});
