Spring Security无法自动关联依赖

标签： spring spring-mvc spring-security

我正在尝试将Spring Security集成到我的Spring MVC项目中。我正在使用的spring版本是4.2。 我自动装配dataSource bean时遇到问题，这是因为WebSecurityConfig类在WebConfig之前调用。

以下是我的WebSecurityConfig代码-

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
@Qualifier("dataSource")
DataSource dataSource;




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

    auth.jdbcAuthentication().dataSource(dataSource).usersByUsernameQuery("select username,password from users where username=?")
        .authoritiesByUsernameQuery("select username, role from user_roles where username=?");


}

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable();
    http.authorizeRequests().antMatchers("/**").hasRole("ADMIN").and()
    .formLogin().loginPage("/login").failureUrl("/login?error")
      .usernameParameter("username").passwordParameter("password")
            .and().logout().logoutRequestMatcher(new AntPathRequestMatcher("/logout"));
}
}

这是WebConfig.java 

@Configuration
@EnableWebMvc
@EnableWebSecurity
@ComponentScan(basePackages = { "com.xyz.abc.*"})

public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
  registry.jsp().prefix("/WEB-INF/views/").suffix(".jsp");
}

@Bean(name = "dataSource")
DataSource dataSource() {
   DataSource dataSource = null;
   JndiTemplate jndi = new JndiTemplate();
   try {
       dataSource = jndi.lookup("java:comp/env/jdbc/GenericDataSource", 
 DataSource.class);
     } catch (NamingException e) {

     }
    return dataSource;
}


@Bean public DefaultAnnotationHandlerMapping 
defaultAnnotationHandlerMapping(){
   DefaultAnnotationHandlerMapping bean = new 
 DefaultAnnotationHandlerMapping();
   bean.setUseDefaultSuffixPattern(false);
    return bean;
  }

   @Bean public AnnotationMethodHandlerAdapter 
 defaultAnnotationMethodHandlerMapping(){
  AnnotationMethodHandlerAdapter bean = new 
AnnotationMethodHandlerAdapter();
   return bean;
}

   @Bean
  public CommonsMultipartResolver multipartResolver() {
    CommonsMultipartResolver resolver=new CommonsMultipartResolver();
    resolver.setDefaultEncoding("utf-8");
    resolver.setMaxUploadSize(52428800);
    return resolver;
}


@Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {

 registry.addResourceHandler("/resources/**").
 addResourceLocations("/static/").setCachePeriod(31556926);
 }

 }

该如何解决？请帮忙。 TIA

我想这是名称冲突，您应该更改bean的名称。类似于“ myDataSourceBean”

另一种方法是使用Primary注释而不是Qualifier
