Question

我有一个基于Eclipse Juno的开发环境，安装了Spring IDE。我的项目也使用Spring Security。我使用的Spring版本是2.5.5，Spring Security是2.0.6。现在，在将Spring IDE从3.1.0更新到3.3.0之后，当Spring编译器尝试编译这一行时，我得到一个NoSuchMethodError：

<security:authentication-provider user-service-ref="userDetailsService" />

<bean id="userDetailsService" class="com.mycompany.security.MyUserDetailsService">
    <property name="daoFactory" ref="DaoFactory" />
</bean>

MyUserDetailsService实现UserDetailsService和InitializingBean。

文件的schemaLocation已定义为：

xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
        http://www.springframework.org/schema/security 
        http://www.springframework.org/schema/security/spring-security-2.0.6.xsd"

stacktrace看起来像这样：

使用Ant脚本编译应用程序并启动服务器时，一切正常，因此问题仅限于Eclipse和Spring IDE。我的Ant和Eclipse配置都使用相同的Spring库。 addConstructorArg方法似乎仍然存在于最新版本的Spring中，所以我对这个错误感到困惑。可能导致这个问题的原因是什么？

Answer 1

我相信这是因为Spring Tools Suite附带了自己的spring库。因此，对于XML解析和验证，它不会在项目类路径上使用库。

请参阅STS-3679

Answer 2

检查XML配置文件以获取Spring和Spring安全性。在xsi：schemaLocation中是否有正确的URL，如：

    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
