问题描述
尝试使用JSR-303（hibernate-validator）验证模型时，我遇到了将 Validator 注入spring应用程序bean的问题
I've got a problem injecting the Validator into the spring application bean when attempting to validate a model using JSR-303 (hibernate-validator)
我的主要配置类是：
@EnableAutoConfiguration
@EnableWebMvc // <---
@EnableJpaRepositories("com.example")
@EntityScan("com.example")
public class MainConfiguration {
根据javadocs：
According to the javadocs:
/**
* Provide a custom {@link Validator} instead of the one created by default.
* The default implementation, assuming JSR-303 is on the classpath, is:
* {@link org.springframework.validation.beanvalidation.LocalValidatorFactoryBean}.
* Leave the return value as {@code null} to keep the default.
*/
Validator getValidator();
Hibernate-validator在类路径上。
我正在尝试将其注入存储库：
Hibernate-validator is on the classpath.I'm trying to inject it into the Repository:
@Repository
public class UserRepositoryImpl implements UserRepositoryCustom {
@Autowired
private Validator validator;
抛出异常：
No qualifying bean of type [javax.validation.Validator] found for dependency:
更新：
这方面的部分解决方法是在主配置类中定义：
The partial work-around for this is to define this in the main configuration class:
@Bean
public Validator validator() {
return new org.springframework.validation.beanvalidation.LocalValidatorFactoryBean();
}
但是集成测试（需要 org。 springframework.test.context.web.WebAppConfiguration; 注释并使用验证逻辑）失败。
But integration tests (the ones which require org.springframework.test.context.web.WebAppConfiguration; annotation and use validation logic) fail.
推荐答案
您需要声明一个类型为 LocalValidatorFactoryBean 的bean，如下所示：
You need to declare a bean of type LocalValidatorFactoryBean like this:
<bean id="validator"
class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>
XML中的
或
in XML or
@Bean
public javax.validation.Validator localValidatorFactoryBean() {
return new LocalValidatorFactoryBean();
}
。
此部分Spring文档包含所有细节
This part of the Spring documentation has all the details
