我一直在研究Spring Boot。当将 spring-boot-starter-security 用于待办事项应用程序时，我尝试使用自定义用户 ID 和密码以及自定义登录页面登录。当我尝试登录时，它不会带我进入下一页。注意:用户名是下一页的必需参数。

我尝试使用下面的方法，但登录后它再次将我带到登录页面作为错误

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/login").permitAll()
                .antMatchers("/", "/*Todo*/**").access("hasRole('USER')").and()
                .formLogin().loginPage("/login").permitAll();
    }

这是我的 securityConfig 代码

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/login").permitAll()
                .antMatchers("/listTodo").hasAnyRole("USER","ADMIN")
                .anyRequest().authenticated()
                .and().formLogin().loginPage("/login").permitAll().and()
                .logout().permitAll();
}
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().withUser("Sudhakar").password("qwe123").roles("USER","ADMIN");
    }
}

I would need to login with user name and get the todo details of the user who logged in. But I am not able to get to next page, after trying many times I am getting below error

java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id "null"

Below is my controller
package com.example.SpringLogin.Controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.SessionAttributes;

import com.example.SpringLogin.service.loginService;

@Controller
@SessionAttributes("name")
public class LoginController {
    @Autowired
    loginService service;

    @RequestMapping(value="/login",method = RequestMethod.POST)
    public String loginMessage(ModelMap model,@RequestParam String name,@RequestParam String password) {
        boolean isValidUser=service.validateUser(name, password);

        if(!isValidUser) {
            model.put("message", "Invalid Credentials");
            return"Room";
        }
        model.put("name", name);
        model.put("password",password);

        return "redirect:/todoList";
    }
    @RequestMapping(value="/login",method = RequestMethod.GET)
    public String roomLogin(ModelMap model, String error) {
        //model.put("name", name);
        if(error!=null) {
            model.addAttribute("errorMsg","UserName or Password is invalid");
        }
        return "Room";
    }
    /*@RequestMapping(value="/login",method = RequestMethod.GET)
    public String showLogin(ModelMap model) {
        //model.put("name", name);
        return "Welcome";
    }*/
    @RequestMapping(value = "/welcome")
    public String showWelcome(ModelMap model) {
        return "login";
    }
}

我的期望是使用用户名登录应用程序并获取用户的待办事项

最佳答案

尝试添加 loginProcessUrl 和 defaultSuccessUrl。像这样的事情:

.formLogin()
.loginPage("/login")
.loginProcessingUrl("/do_login")
.defaultSuccessUrl("/index")

此示例中的索引是您希望在成功登录后进入的页面。
