我试图设置注释验证器来验证对象,而不使用验证器类。起初,我只包含了validator-api 2.0.1.Final库,一切似乎都可以正常运行,但是无法验证对象。
经过研究,我发现我需要添加:
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>
对于调度程序servlet,但这是我非常头痛的时候。之后,出现错误
然后,我将最新版本的休眠验证器添加到项目中,然后出现此错误。
java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.validator.internal.engine.ConfigurationImpl
尝试解决错误,我尝试添加和删除不同的库和事物,并更改库的版本。我最终在我的项目中有了这些库,而且我没有使用maven来处理依赖关系,这使我很难发现错误。这是我在项目中拥有的库:
我花了几个小时来更改库,这是我认为可能可行的最终结果,但是没有用。我错过了重要的事情吗?
我的控制器:
@RequestMapping(value = "/add.html", method = RequestMethod.POST)
public ModelAndView addStaff(@Valid @ModelAttribute Staff staff,
BindingResult result,
HttpServletRequest request,
HttpServletResponse response) throws Exception {
if(result.hasErrors()){
return new ModelAndView(parentFolder + "addStaff", "staff", staff);
}
return new ModelAndView( parentFolder + "addStaff", "staff", new Staff());
}
我的表格:
<div class="form-style">
<div class="form-group">
<form:label path="id">Staff ID</form:label>
<form:input path="id" type="text" class="form-control" placeholder="0123"/>

我认为这可能是类路径的问题,但是在类路径中添加额外的目录似乎根本不起作用。我不知道我在那儿想念什么。
答案 0 :(得分:1)
搜索并尝试了几个小时之后,我终于解决了问题。原来,我缺少一些库,导致NoClassDefFoundError错误。
这是我在项目中使用的库的列表:
解决此问题后,弹出另一个错误NoProviderFoundException。 这是由代码行引起的
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>
我已添加到调度程序servlet。经过一些故障排除后,我找到了解决方案 https://hibernate.atlassian.net/browse/HV-1495有人提及旧的组ID问题。我试图检查我的图书馆组ID,发现
org.hibernate
但是新的组ID是
org.hibernate.validator
因此,我将库更改为正确的组ID,并且一切正常。 并且我还删除了添加到调度程序servlet中的代码行,因为问题仍然存在。即使删除它,该程序仍然可以运行。
答案 1 :(得分:0)
您可以尝试删除javax.el-api-3.0.0.jar
吗?另一个jar已包含API和实现,并且可能导致冲突。
