Spring安全性j_spring_security_check调用给出404未找到错误[关闭]

Question

我正在尝试使用spring security创建登录身份验证。我收到了404登录url /knowledgeBase/j_spring_security_check未找到的错误。我已经在安全xml中正确定义了我的自定义过滤器和我的URL。我还在web xml文件中添加了一个安全过滤器。我通过序列化表单数据通过ajax请求调用此url。我已经成功地在另一个项目中使用此代码，但现在我收到此错误。可能是什么原因？

这是security.xml文件

这是我的登录表单：

<form id="login-form">
                        <div class="form-group">
                            <label>Username</label>
                            <input type="text" class="form-control" name="j_username" ng-model="username"
                                   placeholder="Your username">
                        </div>

                        <div class="form-group">
                            <label>Password</label>
                            <input type="password" name="j_password" class="form-control" ng-model="password"
                                   placeholder="Password">
                        </div>
                        <div class="form-check">
                            <!--<input type="checkbox" class="form-check-input" id="exampleCheck1">-->
                            <!--<label class="form-check-label">Check me out</label>-->
                        </div>
                        <span class="validation-message" style="display:none;">{{validationMessage}}</span>
                        <span class="success-message" style="display:none;">{{successMessage}}</span>
                        <input type="button" class="btn btn-default blue" value="Log in"
                               ng-click="login()">
                    </form>

这就是我通过ajax调用j_spring_security_check网址的方式：

$.ajax({
                            type: "POST",
                            url: 'knowledgeBase/j_spring_security_check',
                            data: jQuery("#login-form").serialize(), // serializes the form's elements.
                            success: function (data) {
                                window.location = "/knowledge-base/memory";
                            },
                            error: function (data, textStatus, jqXHR) {
                                if (data.status == 410) {
                                } else if (data.status == 409) {
                                } else if (data.status == 406) {
                                } else {
                                }

                                $scope.$digest();

                                printError(textStatus);
                            }
                        });

但我收到404未找到错误。

更新：

解决这个问题后，我的UserService出现问题。它无法识别其中定义的自动连接依赖项。我尝试直接在变量和构造函数上使用Autowired注释。 knowledgbaseDao在loadUserByUsername中无效。在启动时，此类的构造函数被调用3次。每个创建不同的对象。第一个是使用默认的空构造函数创建的。其他两个是使用自动装配的构造函数创建的，并为knowledgebaseDao指定正确的类。当从登录页面调用userservice时，它使用第一个UserService类并抛出空指针异常。这是我的代码：

@Component("userService")
public class UserService implements UserDetailsService {
    private static final Logger logger = LoggerFactory.getLogger(UserService.class);

    private KnowledgeBaseDao knowledgeBaseDao;

    public UserService(){
        System.out.println();
    }

    @Autowired
    public UserService(KnowledgeBaseDao knowledgeBaseDao) {
        this.knowledgeBaseDao = knowledgeBaseDao;
        }

    public UserDetails loadUserByUsername(String login) throws AuthenticationException {
        logger.info("UserDetails Database Service : " + login);

        // check user exists in database
        User user = knowledgeBaseDao.findUserByEmail(login);
        if (user == null) {
            logger.warn("User({}) does not exist in system", login);
            throw new UsernameNotFoundException("There is no user with this username.");
        }

        boolean containsLoginRole = checkLoginRole(user);

        if (!containsLoginRole) {
            throw new UsernameNotFoundException("Access denied.");
        }

        if ((user.getStatus() == null || user.getStatus() == 0)) {
            throw new UsernameNotFoundException("User is not confirmed");
        }

        //boolean enabled = user.getStatus() == AccountStatus.ACTIVE;
        boolean accountNonExpired = true;
        boolean credentialsNonExpired = true;
        boolean accountNonLocked = true;

        if (user.getLoginTryCount() != null && user.getLoginTryCount() >= 3) {
            accountNonLocked = false;
        }

        return new org.springframework.security.core.userdetails.User(user.getEmail(), user.getPassword(), true, accountNonExpired,
                credentialsNonExpired, accountNonLocked, this.getAuthorities(user.getRoleId()));
    }

    public Collection<? extends GrantedAuthority> getAuthorities(Collection<Role> roleList) {
        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        for (Role role : roleList) {
            authorities.add(new SimpleGrantedAuthority(role.getName()));
        }
        return authorities;
    }

    public Collection<? extends GrantedAuthority> getAuthorities(Long roleId) {
        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();

        authorities.add(new SimpleGrantedAuthority(Constants.ROLE_NAME(roleId.intValue())));

        return authorities;
    }

    private boolean checkLoginRole(User user) {
        if (user.getRoleId() == 0) {
            return false;
        }

        if (user.getRoleId() == Constants.ROLE_ADMIN
                || user.getRoleId() == Constants.ROLE_MODERATOR
                || user.getRoleId() == Constants.ROLE_USER) {
            return true;
        } else {
            return false;
        }
    }
}
