Java Spring4和Hibernate5方法参数验证

如何使用Hibernate验证传入参数

在XML中

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>
<bean class="org.springframework.validation.beanvalidation.MethodValidationPostProcessor">
    <property name="validator" ref="validator"/>
</bean>

---

这种方法不起作用，我调用带有错误参数的方法，验证不起作用。

问题澄清

将Hibernate Validator（HV）4.2与Spring MVC 4一起使用时，例如使用依赖项：

dependencies {
    providedCompile 'javax.servlet:javax.servlet-api:3.0.1'
    compile 'org.springframework:spring-webmvc:4.0.3.RELEASE'
    compile 'org.hibernate:hibernate-validator:4.2.0.Final'
    runtime 'javax.servlet:jstl:1.1.2'
}

通过在配置文件中声明以下bean，可以告诉Spring自动使用HV验证带有

@Validated

（如asker的示例）注释的类的方法调用

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>
<bean class="org.springframework.validation.beanvalidation.MethodValidationPostProcessor"/>

但问题是如果您将依赖项从上面更改为

dependecies {
    providedCompile 'javax.servlet:javax.servlet-api:3.0.1'
    compile 'org.springframework:spring-webmvc:4.0.3.RELEASE'
    compile 'org.hibernate:hibernate-validator:5.1.0.Final' //**note the change here**
    runtime 'javax.servlet:jstl:1.1.2'
}

然后您将得到一个错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'org.springframework.validation.beanvalidation.MethodValidationPostProcessor#0'
defined in class path resource [spring/config/web/main-config.xml]: Invocation of init
method failed; nested exception is javax.validation.ValidationException: Unable to
instantiate Configuration.

解决方案

向类路径添加2个额外的依赖项，如下所示

dependecies {
    providedCompile 'javax.servlet:javax.servlet-api:3.0.1'
    providedCompile 'javax.el:el-api:2.2'
    providedCompile 'org.glassfish.web:el-impl:2.2'
    compile 'org.springframework:spring-webmvc:4.0.3.RELEASE'
    compile 'org.hibernate:hibernate-validator:5.1.0.Final' //**note the change here**
    runtime 'javax.servlet:jstl:1.1.2'
}

而验证将重现生机。但这一次，它没有引发

MethodConstraintViolationException

，而是引发了

ConstranitViolationException

，没有任何违反的细节

我不确定Spring如何在内部管理这个异常，以及您是否可以从这个异常中展开违规细节。HV 5不再支持

MethodConstraintViolationException

及其相关功能，例如

MethodValidator

，

MethodConstraintViolation

。这与BV 1.0的方法级验证有所不同。我建议您自己使用aspect和

ExecutableValidator

（而不是旧的

MethodValidator

）创建验证服务，如中所述

请注意，如果您尝试像这样获取验证器

ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
ExecutableValidator executableValidator = factory.getValidator().forExecutables();

您可能会得到

ValidationException:无法实例化配置。

我可以通过这样做来解决这个问题

ValidatorFactory factory = Validation.byProvider(HibernateValidator.class).configure().buildValidatorFactory();
ExecutableValidator executableValidator = factory.getValidator().forExecutables();

除了spring和maven pom文件中的其他项目依赖项之外，我还包括以下内容

<properties>
    <hibernate.version>4.3.1.Final</hibernate.version>
    <hibernate.validator.version>5.1.0.Final</hibernate.validator.version>

LocalVariableTableParameterNameDiscoveryer与ASM合作，在ConstraintViolationException中提供正确的参数名称，验证失败时将引发该异常。

显然，Spring建议不要使用ExecutableValidator，而是使用MethodValidationInterceptor，请参阅javadoc:

对于当前版本，您不必添加“asinkxcoswt”编写的所有bean

在pom.xml中添加以下内容：

<dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-validator</artifactId>
   <version>5.3.4.Final</version>
</dependency>
<dependency>
   <groupId>org.glassfish.web</groupId>
   <artifactId>javax.el</artifactId>
   <version>2.2.4</version>
</dependency>

这里没有问题。在hibernate 4.2.0中，malidate方法的packacge org.hibernate.validator.method如何使用hibernate validator 5.0.3I进行验证面临相同的问题。这不起作用，因为您初始化了spring消息源。这是因为验证是hibernate的默认属性名。您可以删除messageSource，它无论如何都会工作..糟糕，您不必使用@Validated注释。验证也可以在没有它的情况下工作。对于

@RequestParam

验证，您只需要

@Validated

。正如JavaDoc所述：“例如，可以与Spring MVC处理程序方法参数一起使用。”我无法使用Hibernate Validator和您提到的设置来验证rest调用的查询参数，验证不会被引入。
