如何在现有的基于XML的Spring MVC项目中使用注释配置Spring安全性？

Question

我是Spring Security的新手，我试图在现有Spring项目中使用注释设置Spring Security（授权和身份验证），但没有获取默认的Spring登录页面。

请告知，我做错了。

我尝试使用xml方法，但工作正常，但是xml和注释方法的组合无法正常工作。

示例web.xml定义为：

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring-mvc-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<!-- Step 2: Set up URL mapping for Spring MVC Dispatcher Servlet -->
<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

spring-mvc-servlet.xml定义为

<!-- Step 1: Add support for component scanning -->
<context:component-scan base-package="com.aditya.delete" />

<!-- Step 2: Add support for conversion, formatting and validation support -->
<mvc:annotation-driven/>

<!-- Step 3: Define Spring MVC view resolver -->
<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/view/" />
    <property name="suffix" value=".jsp" />
</bean>

我的配置类定义为：

    @Configuration
    @EnableWebSecurity
    public class DemoSecurityConfig extends WebSecurityConfigurerAdapter {

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {

    UserBuilder users = User.withDefaultPasswordEncoder();

    auth.inMemoryAuthentication().withUser(users.username("aditya").password("abc").roles("EMPLOYEE"));

}

和扩展AbstractSecurityWebApplicationInitializer的类定义为：

    public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {}

控制器定义为：

    @Controller
    public class MyWebController {


@RequestMapping
public String showHome() {

    return "home";
}

}

当我运行Web应用程序时，它直接重定向到我的home.jsp页面，而不是重定向到默认的spring登录页面。
