Issue
I'm using Spring-Security 5 to secure my web app. I access /login.jsp and fill in username and password, and then click "Log in" to submit the form, and then was redirected to /login.jsp. I see the reponse status code of that http traffic in fiddler is 302.
SecurityConfig class:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private DataSource dataSource;
@Autowired
protected SecurityConfig(DataSource dataSource
) {
this.dataSource = dataSource;
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login.jsp")
.loginProcessingUrl("/login")
.permitAll();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.jdbcAuthentication()
.dataSource(dataSource)
.usersByUsernameQuery("select name userName, password, enabled from user where name=?")
.authoritiesByUsernameQuery("select name userName 'ROLE_USER' from user where name=?")
;
}
}
login.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c"
uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<c:url value="/login" var="loginUrl"/>
<form action="${loginUrl}" method="post"> 1
<c:if test="${param.error != null}"> 2
<p>
Invalid username and password.
</p>
</c:if>
<c:if test="${param.logout != null}"> 3
<p>
You have been logged out.
</p>
</c:if>
<p>
<label for="username">Username</label>
<input type="text" id="username" name="username"/> 4
</p>
<p>
<label for="password">Password</label>
<input type="password" id="password" name="password"/> 5
</p>
<button type="submit" class="btn">Log in</button>
</form>
</body>
</html>
Solution
This is because spring default authentication success handler looks for a url to redirect. What one can do is use a custom AuthenticationSuccessHandler
i have used below and no redirects are happening.
public class AppAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler{
protected void handle(HttpServletRequest request, HttpServletResponse response,
Authentication authentication) throws IOException, ServletException {
}
}
Then define the bean and give it in the configure method for security
@Bean
public AuthenticationSuccessHandler appAuthenticationSuccessHandler(){
return new AppAuthenticationSuccessHandler();
}
Configure method
http
.authorizeRequests()
.antMatchers("/login*")
.permitAll()
.anyRequest()
.authenticated()
.and()
.formLogin()
.successHandler(new appAuthenticationSuccessHandler());
