java - Spring 3 + Tomcat 6 : Form validation exception - java. lang.NoSuchMethodError : javax. el.ExpressionFactory.newInstance()Ljavax/el/ExpressionFactory;

Question

我是 Spring 3 MVC 的新手，正在尝试使用 Java 验证 API 和 Hibernate Validator 实现 JAR 进行表单验证。我正在为我的应用程序使用 Tomcat 6。下面是 pom.xml:

<properties>  
<spring.version>3.1.1.RELEASE</spring.version>  
<jdk.version>1.6</jdk.version>  
</properties>

<dependencies>  

    <dependency>

        <artifactId>spring-core</artifactId>  
        <version>${spring.version}</version>  
    </dependency>  

    <dependency>  
        <groupId>org.springframework</groupId>  
        <artifactId>spring-web</artifactId>

    </dependency>  

    <dependency>  
        <groupId>org.springframework</groupId>  
        <artifactId>spring-webmvc</artifactId>  
        <version>${spring.version}</version>  
    </dependency>  

    <!-- CGLIB is required to process @Configuration classes -->  
    <dependency>
    <groupId>cglib</groupId>
    <artifactId>cglib</artifactId>
    <version>2.2.2</version>
</dependency>

    <version>1.2</version>
</dependency>

    <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
</dependency>            

    <dependency>  
        <groupId>junit</groupId>  
        <artifactId>junit</artifactId>  
        <version>3.8.1</version>  
        <scope>test</scope>  
    </dependency>  
    <dependency>
        <groupId>javax.validation</groupId>
        <artifactId>validation-api</artifactId>
        <version>1.1.0.Final</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>5.0.1.Final</version>
    </dependency>
       </dependencies>  

下面是模型类Employee.java:

@Size(min=2,max=30)
private String name;
@NotEmpty @Email
private String email;
@NotNull @Min(18) @Max(35)
private Integer age;
@Size(min=10)
private String phone;
// Getters and Setters

下面是包含表单的JSP:

<form:form method="post" commandName="empl" action="validate">
<table>
    <tr>
        <td>
            <label for="nameInput">Name:</label>
        </td>
        <td>
            <form:input path="name" id="nameInput"/>
            <form:errors path="name"></form:errors>
        </td>
    </tr>
    <tr>
        <td>
            <label for="ageInput">Age:</label>
        </td>
        <td>
            <form:input path="age" id="ageInput"/>
            <form:errors path="age"></form:errors>
        </td>
    </tr>
    <tr>
        <td>
            <label for="phoneInput">Phone:</label>
        </td>
        <td>
            <form:input path="phone" id="phoneInput"/>
            <form:errors path="phone"></form:errors>
        </td>
    </tr>
    <tr>
        <td>
            <label for="emailInput">Email:</label>
        </td>
        <td>
            <form:input path="email" id="emailInput"/>
            <form:errors path="email"></form:errors>
        </td>
    </tr>
    <%--<tr>
        <td>
            <label for="birthdayInput">Birthday:</label>
        </td>
        <td>
            <form:input path="birthday" id="birthdayInput" placeholder="MM/DD/YYYY"/>
            <form:errors path="birthday"></form:errors>
        </td>
    </tr>
     <tr>
        <td>
            <label for="genderInput">Birthday:</label>
        </td>
        <td>
            <form:select id="genderInput" path="" items="${gender }">      </form:select>
            <form:errors path="birthday"></form:errors>
        </td>
    </tr> --%>
    <tr>
        <td colspan="2">
            <input type="submit" value="Submit">
        </td>
    </tr>
</table>
</form:form>

当我单击提交 按钮时出现错误。甚至不调用 Controller 处理程序方法并抛出以下错误:

我尝试添加以下依赖项但没有用(因此后来将其删除):

<dependency>
        <groupId>javax.el</groupId>
        <artifactId>el-api</artifactId>
        <version>2.2</version>
    </dependency>

请告知如何解决此问题。

如果我添加此依赖项(但没有用，因此也将其删除):

<dependency>
    <groupId>org.glassfish.web</groupId>
    <artifactId>el-impl</artifactId>
    <version>2.2</version>
</dependency>

然后我收到以下错误:

下面是 jar 的快照:

Answer 1

问题是 Tomcat 6 附带了旧版本的 EL (2.1)，而 Hibernate Validator 5.x 需要更新的 EL 2.2。看看:http://hibernate.org/validator/faq/#does-hibernate-validator-5-x-work-with-tomcat-6 .
