在WebSphere上使用Spring(MVC)验证JSR 303

Question

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

在添加Spring特定的配置之前，没有进行任何验证，但也没有任何错误。可能根本没有尝试验证。

现在我已经添加了必要的@Validated类注释和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

首先，您必须强制使用附带的Hibernate Validator5，而不是WebLogic Validator5。只需添加web-inf/validation.xml即可

<?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>

最有可能的是，您需要在deployment.xml中将classloaderMode设置为PARENT_LAST。在耳朵的情况下，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>

我不确定，但我将Validation-API1.1.0打包到WAR，它对我有效。
