spring boot 1.4默認使用 hibernate validator 5.2.4 Final實現校驗功能。hibernate validator 5.2.4 Final是JSR 349 Bean Validation 1.1的具體實現。

How to disable Hibernate validation in a Spring Boot project
As [M. Deinum] mentioned in a comment on my original post, the solution is to set:
spring.jpa.properties.javax.persistence.validation.mode=none
In the application.properties file.
Additionally, this behaviour is described here (its easy to miss because no example is provided).

一 初步使用
hibernate vilidator主要使用注解的方式對bean進行校驗，初步的例子如下所示：
package com.query; import javax.validation.constraints.Min; import org.hibernate.validator.constraints.NotBlank; public class Student { //在需要校驗的字段上指定約束條件 @NotBlankprivate String name;@Min(3)private int age;@NotBlankprivate String classess;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getClassess() {return classess;}public void setClassess(String classess) {this.classess = classess;}}
?
然后在controller中可以這樣調用，加上@Validated注解即可。
package com.controller;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import com.learn.validate.domain.Student;@RestController
public class ValidateController {@RequestMapping(value="testStudent")public void testStudent(@Validated Student student) {}
}
如果校驗失敗，默認會返回Spring boot 框架的出錯信息。是一個json串，里面有詳細的出錯描述。二 使用gruops 屬性來實現區別不同的校驗需求
在上面的例子中，如果Student bean想要用于兩個不同的請求中，每個請求有不同的校驗需求，例如一個請求只需要校驗name字段,一個請求需要校驗name和age兩個字段，那該怎么做呢？
使用注解的groups屬性可以很好的解決這個問題,如下所示：
package com.query; import javax.validation.constraints.Min;import org.hibernate.validator.constraints.NotBlank;public class Student {//使用groups屬性來給分組命名，然后在需要的地方指定命令即可@NotBlank(groups=NAME.class)private String name;@Min(value=3,groups=AGE.class)private int age;@NotBlankprivate String classess;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getClassess() {return classess;}public void setClassess(String classess) {this.classess = classess;}public interface NAME{};public interface AGE{};}
?
根據需要在@Validated屬性中指定需要校驗的分組名，可以指定1到多個。指定到的分組名會全部進行校驗，不指定的不校驗。
package com.controller;import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import com.learn.validate.domain.Student;
import com.learn.validate.domain.Student.AGE;
import com.learn.validate.domain.Student.NAME;@RestController
public class ValidateController {@RequestMapping(value="testStudent")public void testStudent(@Validated Student student) {}@RequestMapping(value="testStudent1")public void testStudent1(@Validated(NAME.class) Student student) {}@RequestMapping(value="testStudent2")public void testStudent2(@Validated({NAME.class,AGE.class}) Student student) {}
}
三 使用 @ScriptAssert 注解校驗復雜的業務邏輯
如果需要校驗的業務邏輯比較復雜，簡單的@NotBlank，@Min注解已經無法滿足需求了，這時可以使用@ScriptAssert來指定進行校驗的方法，通過方法來進行復雜業務邏輯的校驗，然后返回 true或false來表明是否校驗成功。
例如下面的例子：
package com.query;
import javax.validation.constraints.Min;import org.hibernate.validator.constraints.NotBlank;
import org.hibernate.validator.constraints.ScriptAssert;import com.learn.validate.domain.Student.CHECK;
//通過script 屬性指定進行校驗的方法，傳遞校驗的參數，
//依然可以通過groups屬性指定分組名稱
@ScriptAssert(lang="javascript",script="com.learn.validate.domain
.Student.checkParams(_this.name,_this.age,_this.classes)",
groups=CHECK.class)
public class Student {@NotBlank(groups=NAME.class)private String name;@Min(value=3,groups=AGE.class)private int age;@NotBlankprivate String classess;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getClassess() {return classess;}public void setClassess(String classess) {this.classess = classess;}public interface NAME{};public interface AGE{};public interface CHECK{};//注意進行校驗的方法要寫成靜態方法，否則會出現 //TypeError: xxx is not a function 的錯誤public static boolean checkParams(String name,int age,String classes) {if(name!=null&&age>8&classes!=null){return true;}else{return false;}}}
在需要的地方，通過分組名稱進行調用package com.controller;import org.springframework.validation.annotation.Validated; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;import com.learn.validate.domain.Student; import com.learn.validate.domain.Student.CHECK;@RestController public class ValidateController {@RequestMapping(value="testStudent3")public void testStudent3(@Validated(CHECK.class) Student student) {} }
