Spring项目错误现在我正在使用Maven

Question

我开始使用Maven将我的JAR引入我的项目中.我有一个Spring项目,我在eclipse中进入maven项目,但我现在收到此错误:

Description Resource    Path    Location    Type
The classes from the spring-security-web jar (or one of its dependencies) are not available. You need these to use <http>: javax.servlet.Filter my-security-context.xml /WebFlowTemplate/src/main/webapp/WEB-INF/spring line 12 Spring Beans Problem

这是我得到它的一行:

<http use-expressions="true">

这是我的my-security-context.xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans 
    xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans"

    <http use-expressions="true">

        <intercept-url access="hasRole('ROLE_USER')"    pattern="/helloworld**" />
        <intercept-url pattern='/*' access='permitAll' />


        <form-login login-page="/login.jsp"
            authentication-failure-url="/login.jsp" 
            default-target-url="/helloworld" />

        <logout logout-success-url="/" />
    </http>

    <authentication-manager>
        <authentication-provider>
            <user-service>
                <user name="user" password="user" authorities="ROLE_USER" />
            </user-service>

        </authentication-provider>
    </authentication-manager>
</beans:beans>

这是我的pom.xml文件.

看起来一切正常,但我不想看到这个错误.有人可以提供一些信息.

Answer 1

我也尝试了很多解决方案来解决这个问题.但是当我查看项目的maven依赖项时,我找到了解决方案(我不是指pom.xml - >我的意思是STS的包浏览器中的dropDown-view).

servlet-api没有条目.

在我的pom.xml中放入以下依赖项解决问题:

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
    </dependency>
