java - 在spring boot starter security中使用自定义登录页面成功登录没有进入下一页
问题描述
我一直在研究弹簧靴。将 spring-boot-starter-security 用于 todo 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,它没有带我进入下一页。注意:用户名是下一页的必填参数。
我尝试在下面使用,但登录后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";
}
}
My login page

return todo;
}

return null;
}
public List<todoList> UpdateTodo(todoList todo){
/*for (todoList td : todos) {
if(td.getId()==todo.getId()) {
td.setCourse(todo.getCourse());
td.setDate(todo.getDate());
}
}*/
todos.remove(todo);
todos.add(todo);
return todos;
}
//it will delete the todo
public void deleteTodo(int id) {
Iterator<todoList> it = todos.iterator();
while(it.hasNext()){
todoList td=it.next();
if(td.getId()==id) {
it.remove();
}
}
}
}
我的期望是使用用户名登录应用程序并获取用户的 todolist
解决方案
尝试添加 aloginProcessUrl
和 a defaultSuccessUrl
。像这样的东西:
.formLogin()
.loginPage("/login")
.loginProcessingUrl("/do_login")
.defaultSuccessUrl("/index")
本例中的 index 是您希望在成功登录后进入的页面。
