創建名爲'validator'的bean時出錯

我試圖創建bean驗證（我正在使用tomcat服務器7）。當我將這段代碼創建名爲'validator'的bean時出錯

@Bean 
public Validator validator() { 
    return new org.springframework.validation.beanvalidation.LocalValidatorFactoryBean(); 
}

我得到了錯誤

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'validator' defined in Config.SpringConfig: Invocation of init method failed; nested exception is javax.validation.ValidationException: HV000183: Unable to initialize 'javax.el.ExpressionFactory'. Check that you have the EL dependencies on the classpath, or use ParameterMessageInterpolator instead

我已經看過了所有的同樣的問題，並添加所需的依賴如下：

<dependency org="javax.el" name="el-api" rev="2.2.1-b04" conf="compile->default"/> 
    <dependency org="org.apache.tomcat" name="tomcat-el-api" rev="8.5.14" conf="compile->default"/> 
    <dependency org="org.apache.tomcat" name="tomcat-jasper-el" rev="8.5.14" conf="compile->default"/> 
    <dependency org="javax.validation" name="validation-api" rev="2.0.0.Final" conf="compile->default"/> 
    <dependency org="org.hibernate" name="hibernate-validator" rev="6.0.0.CR2" conf="compile->default"/>

但問題仍然發生。

請幫助我，非常感謝

檢查，如果你不具備javax.el 2個不同的版本不兼容。嘗試生成依賴樹來查看衝突。

例如：

<dependency org="javax.el" name="el-api" rev="2.2.1-b04" conf="compile->default"/> 
<dependency org="org.apache.tomcat" name="tomcat-el-api" rev="8.5.14" conf="compile->default"/> 
<dependency org="org.apache.tomcat" name="tomcat-jasper-el" rev="8.5.14" conf="compile->default"/>

可以提供不同版本的API。

嘗試刪除javax.el也。

我試圖同時刪除javax.el但它好好嘗試的工作。 :( – nptn

Chcek如果依賴關係提供了不同版本的javax.el和javax.validation（spring，tomcat，hibernate）並調整這些依賴關係 – Athlan

哦，非常感謝所以我使用的是Tomcat 7，我應該從哪個版本開始？ – nptn

您可以查看Hibernate Validator的getting started頁面。看起來您正在嘗試使用HV 6.0，它取決於javax-el的3.0版本（如果您使用EL進行消息插值）。你正在添加2.2版本。所以這可能是你看到這個錯誤的原因。還有一個最終版本的HV 6.0發佈，所以你可以使用它來代替CR2。

它應該是足有：

<dependency org="org.glassfish" name="javax.el" rev="3.0.1-b08" conf="compile->default"/> 
<dependency org="org.hibernate" name="hibernate-validator" rev="6.0.1.Final" conf="compile->default"/>

非常感謝，我會嘗試一下 – nptn

我改變了它，並收到此錯誤：在類org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration中定義的名稱爲'requestMappingHandlerAdapter'的bean時出錯錯誤：通過工廠實例化Bean方法失敗 – nptn

很難說這麼少的信息有什麼問題，我假設你提到的錯誤是頂級錯誤，如果是這樣，應該有一個原因爲什麼它沒有創建該bean ... –
