JSR 303在WebSphere上验证Spring（MVC）

Question

我试图在WAS 8.5.5.12完整配置文件中使用Spring MVC控制器进行JSR 303 bean验证。

我确认只是一个单一的@RequestParam，不是一个完整的bean：

@RequestMapping(method=RequestMethod.GET) 
public String initializeCheckIn(
    @Valid @Pattern(regexp = "^[\\p{Alnum}]*$") 
    @RequestParam("officeid") String officeId, HttpSession session, Model model) { 

我加了一些Spring-specific configuration之前，没有验证正在发生，但是没有任何错误。据推测，验证并没有被尝试。

现在，我已经添加了必要的@Validated类注解和bean定义：

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

我得到以下错误：

[8/9/17 10:33:40:588 CDT] 000000a7 ServletWrappe E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0014E: Uncaught service() exception root cause Spring MVC Dispatcher: org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: org.hibernate.validator.method.MethodConstraintViolationException 
...

     at my.package.web.CheckInController$$EnhancerBySpringCGLIB$$d385737c.initializeCheckIn(<generated>) 

基于

http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/validation/beanvalidation/MethodValidationPostProcessor.html

Spring应该自动检测一个可用的JSR-303提供者，其中this version of WebSphere (8.5.5.12 full profile) should have。它似乎无法找到JSR-303提供者，所以它回落到默认值。

那么，为什么没有找到WebSphere版本或者如何找到它？

Answer 1

首先，您必须强制使用发运的Hibernate Validator 5而不是WebLogic。只需添加WEB-INF/validation.xml中

<?xml version="1.0" encoding="UTF-8"?> 
<validation-config 
    xmlns="http://jboss.org/xml/ns/javax/validation/configuration" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://jboss.org/xml/ns/javax/validation/configuration http://www.jboss.org/xml/ns/javax/validation/configuration/validation-configuration-1.0.xsd"> 

    <default-provider>org.hibernate.validator.HibernateValidator</default-provider> 
</validation-config> 

最可能的是，你需要设置classloaderMode在deployment.xml中到PARENT_LAST。在EAR的情况下，它应该看起来像

<?xml version="1.0" encoding="UTF-8"?> 
<appdeployment:Deployment xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:appdeployment="http://www.ibm.com/websphere/appserver/schemas/5.0/appdeployment.xmi" xmi:id="Deployment_1"> 
    <deployedObject xmi:type="appdeployment:ApplicationDeployment" xmi:id="ApplicationDeployment_1" deploymentId="0" startingWeight="1"> 
    <modules xmi:type="appdeployment:WebModuleDeployment" xmi:id="WebModuleDeployment_1" deploymentId="1" startingWeight="10000" uri="foureyes-ri.war" classloaderMode="PARENT_LAST"/> 
    </deployedObject> 
</appdeployment:Deployment> 

我不知道，但我包验证的API 1.1.0战争，它为我工作。
