Java 无法使用BCryptPasswordEncoder登录

我正在使用spring安全加密，但无法登录。 我的spring-security.xml是

  <?xml version="1.0" encoding="UTF-8"?>
 < beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:security="http://www.springframework.org/schema/security"

    <security:logout logout-success-url="/logout" />

</security:http>

<security:authentication-manager>
  <security:authentication-provider>

    <security:jdbc-user-service data-source-ref="dataSource"
            users-by-username-query=
                "select username,password, enabled from USER_MASTER where username=?"
            authorities-by-username-query=
                "select username,USER_ROLE from USER_ROLE where username =?  " />
                <security:password-encoder ref="passwordEncoder"/>

</security:authentication-manager>

<bean id="passwordEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder" >
        <constructor-arg name="strength" value="12" />
</bean>

我的jsp表单是

 <form name='loginForm' class="form-signin" action="<c:url value='j_spring_security_check' />" method="post"> 

  <h2 class="form-signin-heading" style="padding-left:120px;">Login</h2>
  <input type="text" class="form-control" ng-model = "username" name="username" placeholder="Email Address" required autofocus />
  <br>
  <input type="password" class="form-control" ng-model = "password" name="j_password" placeholder="Password" required/>      
  <br>
  <input name="submit" type="submit"
                    value="submit" />

  <a href="" style="padding-left:100px;">Forgot Password</a>  
  <input type="hidden" name="${_csrf.parameterName}"
            value="${_csrf.token}" />

</form>

登录

但我无法登录。登录时我甚至没有遇到异常。是否有任何设置需要执行更多操作，或者配置中是否存在任何错误。

调试日志是什么样子的？您是否尝试将调试点添加到BCryptPasswordEncoder？将spring security log level设置为debug并再次尝试使其在没有bcrypt编码器的情况下工作？是的，没有加密，它工作正常。生成并存储在数据库中，但我必须保留调试点，因为检索和检查将由spring-security.xml负责
