我应该添加什么来使它正确？

【问题讨论】：

Spring security 4 custom login j_spring_security_check return http 302的可能重复

标签： java spring spring-mvc spring-security

【解决方案1】：

检查 csrf 令牌

如果你使用带有post url的表单标签，你应该使用token参数发送

<form>
  <input type="hidden" th:name="${_csrf.parameterName}" th:value="${_csrf.token}"/>
</form>

或

@Configuration
@EnableWebSecurity
@EnableOAuth2Sso
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
http
    .csrf().disable()

安全配置中应该允许url

@Configuration
@EnableWebSecurity
@EnableOAuth2Sso
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
http
    .csrf().disable()
    .authorizeRequests()
    .antMatchers(HttpMethod.POST, "/j_spring_security_check").permitAll()

【讨论】：

我应该在哪里放置表单标签？在security-context.xml?
in
" method="post"> 标签

【解决方案2】：

因为request不包含csrftoken，由于spring security自动开启，csrftoken必须随request一起发送。简单地禁用它不是一个好主意，这会使整个应用程序完全打开。

在表单中添加以下隐藏输入，

<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>

如果您想禁用csrf 支持，请在security-context.xml 中使用它。（春季 4+）

<http>
    <csrf disabled="true"/>
</http>

【讨论】：

哪个更好？
@pipilam 我会使用 csrf 令牌，但这取决于
@pipilam 你需要把这个<input>粘贴到html中<form>
现在我遇到了另一个错误，即No mapping found for HTTP request with URI [/j_spring_security_check] in DispatcherServlet with name 'DefaultServlet'。一切都应该正常...
@pipilam 尝试 /login 代替
