Spring验证默认消息

问题描述

我需要在控制器中以编程方式获取解决的错误消息。 typeMismatch错误的默认验证消息不会从我的messages.properties文件中填充。我有一个表单支持对象，其中一个字段是一个整数。如果我为该字段提交一个字符串，我得到：

 无法将类型java.lang.String的属性值转换为属性establishedYear需要输入java.lang.Integer;嵌套异常是java.lang.NumberFormatException：对于输入字符串：1995a
  

作为默认消息ObjectError。这是我的控制器输出：

  @RequestMapping（method = RequestMethod.POST）
 public @ResponseBody FormJSONResponse postForm @Valid ProfileEditCompanyForm profileEditCompanyForm，BindingResult result）throws Exception {
 if（result.hasErrors（））{
 for（ObjectError objectError：result.getAllErrors（））{
 System.out.println objectError.getDefaultMessage（））; //这不是我的信息，但应该是
} 
} 
 ...其他东西... 
} 
  / pre> 
 
 
所以我添加了一个messages.properties到WEB-INF /类与一些测试消息，看看是否可以覆盖该默认消息：
  typeMismatch.profileEditCompanyForm.establishedYear = test 1 
 typeMismatch.establishedYear = test 2 
 typeMismatch.java.lang.Integer = test 3 
 typeMismatch = test 4 
 profileEditCompanyForm.establishedYear = test 5 
 establishedYear = test 6 
  
在我的app-servlet.xml文件中，我有：
 < mvc：注释驱动的转换服务=conversionServicevalidator =validator/> 
 
< bean id =messageSourceclass =org.springframework.context.support.ResourceBundleMessageSource> 
< property name =basenamevalue =messages/> 
< / bean> 
 
< bean id =validatorclass =org.springframework.validation.beanvalidation.LocalValidatorFactoryBean> 
< property name =validationMessageSourceref =messageSource/> 
< / bean> 
  
为什么不从我的messages.properties文件中收到我的任何邮件？
解决方案
在你的Spring context中尝试这个：
 < bean id =messageSource
 class =org.springframework.context.support.ReloadableResourceBundleMessageSource> 
< property name =basenamevalue =WEB-INF / classes / messages/> 
< / bean> 
  
然后在WEB-INF / classes文件夹内创建一个文件调用：messages.properties / p> 
 
 
记录您必须提供的messages.properties的内容：
  typeMismatch.pathValueInsideYourJSPform：input =您的消息
  
希望这有助于您！ / p>

I need to get the resolved error messages programmatically in the controller.  The default validation message for typeMismatch errors are not populating from my messages.properties file.  I have a form backing object where a field is an Integer.  If I submit a string for that field I get:
Failed to convert property value of type 'java.lang.String' to required type 'java.lang.Integer' for property 'establishedYear'; nested exception is java.lang.NumberFormatException: For input string: "1995a"
as the default message in the ObjectError.  Here's my controller that output it:
  @RequestMapping(method = RequestMethod.POST)
  public @ResponseBody FormJSONResponse postForm(@Valid ProfileEditCompanyForm profileEditCompanyForm, BindingResult result) throws Exception {
    if (result.hasErrors()) {
      for (ObjectError objectError : result.getAllErrors()) {
        System.out.println(objectError.getDefaultMessage());  // THIS IS NOT MY MESSAGE, BUT SHOULD BE
      }
    }
    ... other stuff ...
  }
So I added a messages.properties to WEB-INF/classes with some test messages to see if I could override that default message:
typeMismatch.profileEditCompanyForm.establishedYear=test 1
typeMismatch.establishedYear=test 2
typeMismatch.java.lang.Integer=test 3
typeMismatch=test 4
profileEditCompanyForm.establishedYear=test 5
establishedYear=test 6
In my app-servlet.xml file I have:
<mvc:annotation-driven conversion-service="conversionService" validator="validator"/>

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
  <property name="basename" value="messages" />
</bean>

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
  <property name="validationMessageSource" ref="messageSource"/>
</bean>
Why isn't it picking up any of my messages from my messages.properties file?
 解决方案 
Try this in you Spring context instead:
<bean id="messageSource"
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="WEB-INF/classes/messages" />
</bean>
Then inside "WEB-INF/classes" folder create a file call: "messages.properties" 
Take note for the content of "messages.properties" you have to provide it like this :
typeMismatch.pathValueInsideYourJSPform:input= Your Message
Hope this helps you !
