尽管它显示了应用程序的第一页，但是当我输入一个地址时，它显示的是以下错误而不是所选页面的内容.

Although, it shows the first page of the application, when I enter an address it shows following error rather than content of the selected page.

我想这个问题与我的依赖关系有关，但不知道如何解决.

I suppose the problem is related to my dependencies but do not know how to solve it.

推荐答案

正如我所期望的那样，问题出在依赖项上.我可以通过更新pom.xml并清理项目来解决该问题.

As I expected the problem was with the dependencies. I could solve the issue by updating my pom.xml and cleaning the project.

pom.xml 

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>Spring2</groupId>
    <artifactId>Spring2</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>Spring2</name>


    <url>http://maven.apache.org</url>
    <properties>
        <spring.version>4.1.5.RELEASE</spring.version>
    </properties>


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

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

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

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.0</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

</project>
