This article shows you how to verify the access parameters of springboot. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Use environment jdk1.8 spring 4 and above 1, add jar package com.github.fashionbrot mars-validated 1.0.2 2, Enable the use of valid 2 ways @ SpringBootApplication@EnableValidatedConfig (fileName = "test") / / fileName the default Chinese jar package comes with it. If you need batch customization, create your own test.properties and put it under resources in your own project, public class DemoApplication {public static void main (String [] args) {SpringApplication.run (DemoApplication.class). Args) }} @ Component@Configuration@EnableValidatedConfig (fileName = "valid_zh_CN") / / read the valid_zh_CN under mars-validated resources by default, so do not write default read Chinese public class ValidConfig {} 3, customize to implement global exception handling

Intercepting ValidatedException exception classes

@ RestControllerAdvice@Slf4jpublic class GlobalExceptionHandler {@ ExceptionHandler (Exception.class) @ ResponseStatus (HttpStatus.OK) public RespVo exception (Exception e) {log.error ("exception error:", e); return RespVo.fail (RespCode.FAIL.getMsg ()) } / * * parameters verify global processing * @ param e * @ return * / @ ExceptionHandler (ValidatedException.class) @ ResponseStatus (HttpStatus.OK) public RespVo ValidationException (ValidatedException e) {if (log.isDebugEnabled ()) {log.debug ("filedName: {} errorMsg: {}", e.getFieldName (), e.getMsg ()) } return RespVo.fail (e.getMsg (), RespCode.PARAMETER_ERROR.getCode ());} 4. Start using @ Validated / / API to enable verification @ Controllerpublic class TestController {@ Autowired private ValidService validService @ RequestMapping ("/ test") @ ResponseBody @ Validated / / API enables verification public String test (String abc,@Custom (min = 1dmsg = "request parameter failed") String abc1) {return abc+ ":" + abc1 } / / group verification parameter @ RequestMapping ("/ test1") @ ResponseBody @ Validated (groups = {EditGroup.class}) public String test1 (@ Custom (min = 1je groups = {EditGroup.class,AddGroup.class}) String abc1) {return abc1 } / / group verifies bean @ RequestMapping ("/ test2") @ ResponseBody @ Validated (groups = AddGroup.class) public String test2 (GroupModel groupModel) {return groupModel.getAbc () }} 5. Note AnnotationSupported data types uses NotBlankString to verify whether the String string is empty NotNullString,Object,Integer,Long,Double,Short,Float,BigDecimal, BigInteger verifies that the object is empty NotEmptyString verification string cannot be empty AssertFalseBoolean,boolean,String can only verify for falseAssertTrueBoolean,boolean,String bank card CreditCardString verify credit card DefaultInteger,Double,Long,Short,Float,BigDecimal,String setting default value DigitsString verification is numeric EmailString verification is mailbox IdCardString verification is ID card Verify 18-year-old Lengthint,long,short,double,Integer,Long,Float,Double,Short,String verification length PatternString regular expression verification PhoneString verification mobile phone number is correct Sizeint,long,short,Integer,Long,Short verification size value NotEqualSizeString verification length 6, custom note (1) definition annotation @ Documented@Target ({ElementType.FIELD, ElementType.PARAMETER}) @ Retention (RetentionPolicy.RUNTIME) @ Constraint (validatedBy = {CustomConstraintValidator.class) CustomConstraintValidator2.class}) / / can correspond to multiple or one implementation class / / CustomConstraintValidator implementation class 1//CustomConstraintValidator2 implementation class 2public @ interface Custom {/ / com.sgr.valid.Custom.msg jar package under valid_zh_CN.properties corresponding msg String msg () default "com.sgr.valid.Custom.msg" Int min (); Class [] groups () default {};} (2) implement class CustomConstraintValidator like CustomConstraintValidator2public class CustomConstraintValidator implements ConstraintValidator {@ Override public boolean isValid (Custom custom, Object var1) {/ * custom method * / int min=custom.min (); / * valud * / System.out.println (var1); var1= "567" / * return true successful false verification failed * / return false;} / / parameters can be modified @ Override public Object modify (Custom annotation, Object var) {System.out.println ("CustomConstraintValidator:" + var); return var+ "1";}}
