Spring Security性-未调用自定义userDetailsService实现

Question

尝试使用自定义userDetailsService学习Spring Security性并面临以下问题

访问受限页（/admin或/user）时，spring security将启动并显示登录页。
但在使用正确的用户名和密码提交登录页后，在调用自定义userDetailsService实现中的loadUserByUsername方法之前，将直接显示拒绝访问页。

在日志中，只有org.springframework.security.access.AccessDeniedException异常--在访问受限页面时，没有其他异常。

代码

@Controller
public class TestController {

    @RequestMapping("/home")
    public String getHomePage() {
        return "home";
    }


    @RequestMapping(value="/user")
    public String getUserPage() {
        return "user";
    }

    @RequestMapping(value="/admin")
    public String getAdminPage() {
        return "admin";
    }
}

安全配置：

            boolean enabled = true;
            boolean accountNonExpired = true;
            boolean credentialsNonExpired = true;

                    credentialsNonExpired, accountNonLocked,
                    getAuthorities(domainUser.getRole().getRole()));

        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    public Collection<? extends GrantedAuthority> getAuthorities(Integer role) {
        List<GrantedAuthority> authList = getGrantedAuthorities(getRoles(role));
        return authList;
    }

    public List<String> getRoles(Integer role) {
        List<String> roles = new ArrayList<String>();

        if (role.intValue() == 1) {
            roles.add("ROLE_USER");
            roles.add("ROLE_ADMIN");

        } else if (role.intValue() == 2) {
            roles.add("ROLE_USER");
        }

        return roles;
    }

    public static List<GrantedAuthority> getGrantedAuthorities(
            List<String> roles) {
        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        for (String role : roles) {

    public UserRepository getUserRepository() {
        return userRepository;
    }

    public void setUserRepository(UserRepository userRepository) {

在http的Spring Security配置中，应更改以下内容：

default-target-url="/abcd"

对某事

default-target-url="/"

或者你定义的任何东西。

• default-target-url定义登录过程成功时的默认位置。
• 确保定义所有必要的intercept-url从最特定到最通用
