Spring：错误连接DataSource java安全配置

Question

我无法在tomcat中破坏我的webapp（基于Spring MVC）。尝试通过JDBC配置安全性时，我收到此错误：

我认为我的java配置没问题，但是出了点问题。我无法找到错误。这是配置文件：

    package com.mycompany.web.configuration;

    import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

WebApplicationInitializer：

public class MycompanyWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] { RootConfig.class };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { WebConfig.class };
    }
}

WebConfig：

package com.mycompany.web.configuration;

import org.springframework.context.annotation.ComponentScan;

        tiles.setCheckRefresh(true);
        return tiles;
    }

    }

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {

    }

}

SecurityConfig

package com.mycompany.web.configuration;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;

/**

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{
    @Autowired
    private DataSource dataSource;

    /**
     * Configura el acceso a la aplicación para los usuarios.
     */
    @Autowired
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        String queryUsers = "SELECT bla bla bla bla";
        String queryAuth = "SELECT bla bla bla";
        auth.jdbcAuthentication().dataSource(dataSource).
            usersByUsernameQuery(queryUsers).
            authoritiesByUsernameQuery(queryAuth);
    }

    /**

     */
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().anyRequest().authenticated().
            and().
            formLogin().loginPage("/").permitAll().failureUrl("/").usernameParameter("username").passwordParameter("password").
            and().
            httpBasic().
            and().
            csrf();
    }

}

Root Config

package com.mycompany.web.configuration;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.ComponentScan.Filter;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@ComponentScan(basePackages={"com.justinfact.web"}, 
               excludeFilters={@Filter(type=FilterType.ANNOTATION, value=EnableWebMvc.class)})
public class RootConfig {
}

Answer 1

请在@Configuration班级中添加@Service和SecurityConfig注释。

@Configuration使类能够注入Bean，@Service注释使类SecurityConfig成为AutoWired。

  

你可以尝试一下......我的知识是有限的，我建议你按照我面临的同样的问题情景..

@Configuration
@Service
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{
    @Autowired
    private DataSource dataSource;

感谢。

Answer 2

通过配置AppInitilizer解决：

package com.mycompany.web.configuration;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class MyCompanytWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        //return new Class<?>[] { RootConfig.class };
        return new Class<?>[] { WebConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }

}
