我試圖用電子郵件，而不是使用Spring Security的UserDetailService驗證用戶名登錄使用UserDetailService郵箱登錄身份驗證，但我不能能夠登錄並獲得在SpringSecurity
org.springframework.security.authentication.InternalAuthenticationServiceException.
當調試代碼，調試器不不去後
Users user = userDao.findByUserName(useremail); from UserServiceImpl.java and occurred error.
可能有一個步驟需要更多的地方。 配置和Java代碼和錯誤日誌如下： -
的applicationContext.xml
<security:http auto-config="true">
<security:intercept-url pattern="/admin/**" access="ROLE_ADMIN" />
<security:intercept-url pattern="/customer/**" access="ROLE_USER" />
<security:form-login login-page="/login"
default-target-url="/product/productList/all" authentication-failure-url="/login?error"
username-parameter="username" password-parameter="password" />
<security:logout logout-success-url="/login?logout" />
</security:http>
<security:authentication-manager>
<security:authentication-provider user-service-ref="userServiceImpl">

<bean id="bcryptEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder" >
<constructor-arg name="strength" value="11" />
</bean>
的Login.jsp
<form name="loginForm" action="<c:url value="/j_spring_security_check" />" method="post">
<c:if test="${not empty error}">
<div class="error" style="color: #ff0000;">${error}</div>

</div>
<input type="submit" value="Submit" class="btn btn-default">

</form>

控制檯錯誤如下：

請幫助我克服通過上面的錯誤。
非常感謝。
我在ApplicationContext.xml中錯誤地將此代碼
