Spring Security login returns 404

I am currently working on my blog in Spring framework. I am implementing the Spring Security for login purpose. Everything works as expected until I submit the login credentials which is always returning 404 code.

Here is my web.xml code

<?xml version="1.0" encoding="UTF-8"?>

Here is my spring security code:

    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/avispring"/>

    <security:form-login        
    login-page="/login.html"
    authentication-failure-url="/login?login_error=1"
    default-target-url="/admin/home.html"/>     
</security:http>

            authorities-by-username-query="select u1.USERNAME,u2.ROLE from USER_AUTHENTICATION u1,USER_AUTHORIZATION u2 where u1.USER_ID=u2.USER_ID and u1.USERNAME=?"/>
    </security:authentication-provider>
</security:authentication-manager>

part of my login.jsp code is

<form action="<c:url value="/login"/>" method="post">
      <div class="form-group has-feedback">
        <input type="email" class="form-control" placeholder="Email" name="username">
        <span class="glyphicon glyphicon-envelope form-control-feedback"></span>
      </div>
      <div class="form-group has-feedback">
        <input type="password" class="form-control" placeholder="Password" name="password">
        <span class="glyphicon glyphicon-lock form-control-feedback"></span>
      </div>
      <div class="row">
        <div class="col-xs-8">
          <div class="checkbox icheck">
            <label>
              <input type="checkbox"> Remember Me
            </label>
          </div>
        </div><!-- /.col -->
        <div class="col-xs-4">
          <button type="submit" class="btn btn-primary btn-block btn-flat"     name="submit">Sign In</button>
        </div><!-- /.col -->
      </div>
    </form>

and the console output is

Oct 16, 2015 1:06:03 AM org.springframework.web.servlet.DispatcherServlet noHandlerFound WARNING: No mapping found for HTTP request with URI [/avispring/login] in DispatcherServlet with name 'spring'

Note:

I am using spring 4.2.1 and spring security 4.0.2
Most of the forums are pointing to the context path i.e [appname/login] or [appname/j_spring_security_check] and I think mine is ok regarding it

Please help...

UPDATE:

when I used log4j, the debug output at the time of form submission is as follows:

回答1:

Ok that was so frustrating and I have found my answer by hit and trial. To all others who are facing my problem I am posting my solution. I had to change only one line in my web.xml file. I had to replace this code

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/admin/*</url-pattern>
</filter-mapping>

with this code

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

and I don't even need this line in spring-security.xml file

<security:intercept-url pattern="/j_spring_security_check" access="permitAll"/>

Hope that might help somebody. Happy coding...

回答2:

Did you try setting the login-processing-url attribute of your <security:form-login> element? I use the same up-to-date versions of Spring and Spring Security as you and I added the login-processing-url attribute as follows:

login-processing-url="/j_spring_security_check"

Everything works properly, and I don't even need the following element:

<security:intercept-url pattern="/j_spring_security_check" access="permitAll"/>

Of course, if you wish to use /login instead of /j_spring_security_check, you are free to do so. Just make sure the URIs you put in your JSP and in your Spring Security configuration file match.

Hope this will help...

------------ UPDATE ------------

I think about it... Spring Security introduced Cross-Site Request Forgery (CSRF) protection in version 4. When I updated my code, in order to avoid adding CSRF management in all my protected JSPs (not necessary for my business needs), I had to add the following element in my <security:http> element:
