Question

我正在学习用apache wicket开发，我试图整合Spring

这是对pom.xml文件

的依赖

</dependency>
        -->
        <dependency>
             <groupId>org.apache.wicket</groupId>
             <artifactId>wicket-spring</artifactId>
             <version>${wicket.version}</version>
        </dependency>
        <!-- spring dependency -->
        <dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-core</artifactId>
           <version>3.0.5.RELEASE</version>
        </dependency>

        <dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-context</artifactId>
           <version>3.0.5.RELEASE</version>
        </dependency>


        <dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-web</artifactId>
           <version>3.0.5.RELEASE</version>
        </dependency>

这是SpringIntegrationPage.java

public class SpringIntegrationPage extends WebPage {

    private static final long serialVersionUID = 1L;
    @ SpringBean(name="userModel")
    private UserModel userModel;
    public SpringIntegrationPage(){
        add(new Label("namelbl", new PropertyModel<String>(userModel, "name")));
        add(new Label("genderlbl", new PropertyModel<String>(userModel, "gender")));
        }
}

我得到org.apache.wicket.WicketRuntimeException：无法使用构造函数＆＃39; public com.beton.SpringIntegrationPage（）实例化页面引起：java.lang.NoClassDefFoundError：org / springframework / core / ResolvableType

org.apache.wicket.WicketRuntimeException: Can't instantiate page using constructor 'public com.beton.SpringIntegrationPage()'. An exception has been thrown during construction!

Caused by: java.lang.NoClassDefFoundError: org/springframework/core/ResolvableType

Answer 1

似乎在Spring 4.0中引入了这种类型（ResolvableType），因此它不会在3.0.5.RELEASE中出现。 check this page

因此，您可能需要考虑升级Spring版本或使用wicket的兼容版本。

java.lang.NoClassDefFoundError：org / springframework / core / ResolvableType
