由于配置错误，无法加载基于Spring的应用程序

Question

I am developing an spring application based in a code from a tutorial, with the objective of learn about spring-security using database. My application, in this moment, is displaying an erro 404 when I try run it from Eclipse with Tomcat7. While in the browser a 404 error page is displayed, in the console of the Eclipse the follow message is observed:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.filterChains': Cannot resolve reference to bean 'org.springframework.security.web.DefaultSecurityFilterChain#0' while setting bean property 'sourceList' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.web.DefaultSecurityFilterChain#0': Cannot resolve reference to bean 'org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter#0' while setting constructor argument with key [3]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter#0': Cannot resolve reference to bean 'org.springframework.security.authentication.ProviderManager#0' while setting bean property 'authenticationManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authentication.ProviderManager#0': Cannot resolve reference to bean 'org.springframework.security.config.authentication.AuthenticationManagerFactoryBean#0' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.authentication.AuthenticationManagerFactoryBean#0': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authenticationManager': Cannot resolve reference to bean 'org.springframework.security.authentication.dao.DaoAuthenticationProvider#0' while setting constructor argument with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authentication.dao.DaoAuthenticationProvider#0': Cannot resolve reference to bean 'org.springframework.security.provisioning.JdbcUserDetailsManager#0' while setting bean property 'userDetailsService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.provisioning.JdbcUserDetailsManager#0': Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dataSource' is defined

Someone can identify any error in this files? I spent many time with them, and still can figure what's wrong.

Answer 1

You can't have two context parameter named contextConfigLocation in your web.xml . To declare multiple context configuration files, you must seperate them with a space.

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/sdnext-servlet.xml
        /WEB-INF/sdnext-security.xml
    </param-value>
</context-param>

Answer 2

If you look at the last line of the stacktrace, it says:-

org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'org.springframework.security.provisioning.JdbcUserDetailsManager#0': Cannot resolve 
reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dataSource' is defined

It seems like you defined that bean in the wrong file.

So, move dataSource bean from sdnext-servlet.xml to sdnext-security.xml first.

In your web.xml, you already have the following configuration:-

<servlet>
    <servlet-name>sdnext</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>

Since the DispatcherServlet's servlet-name is sdnext , by default, Spring MVC will automatically look for sdnext-servlet.xml under /WEB-INF folder. That said, you can safely remove this configuration below from web.xml because 1) Spring MVC is already finding that configuration file by itself and 2) contextConfigLocation is used only by Spring, not Spring MVC, so there's no point exposing servlet related configuration here:-

<!-- Delete this! -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/sdnext-servlet.xml</param-value>
</context-param>

So, your web.xml should have exactly one contextConfigLocation pointing to /WEB-INF/sdnext-security.xml , which you already have.
