出现意外错误（404 Not Found）JSP 和 Spring Boot

Question

当我尝试将一个项目翻译成 Spring Boot 时，我得到一个错误——我无法理解我做错了什么。 添加到property-file中的后缀和前缀，试图改变jsp的位置，debager显示在controller的方法中来了。 我做错了什么？如果有任何帮助，我将不胜感激

错误：

Whitelabel 错误页面 此应用程序没有明确的映射 /error，因此您将其视为后备。

2018 年 7 月 17 日星期二 00:45:23 EEST 出现意外错误（type=Not 找到，状态=404）。 /Authorization.jsp

Spring Boot application.properties：

Sping Security 配置：（以防万一）

package com.solopov.hillel.uquiz.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

import javax.sql.DataSource;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Autowired
    DataSource dataSource;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.jdbcAuthentication().dataSource(dataSource).passwordEncoder(new BCryptPasswordEncoder())
            .usersByUsernameQuery("select login,password,true from user where login=?")
             .authoritiesByUsernameQuery("select login, role from user where login=?");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http    .authorizeRequests()
                .antMatchers("/auth", "/reg","/welcomepage").permitAll()
                .antMatchers("/admin/**").hasAuthority("admin")
                .anyRequest().authenticated().and()
                .formLogin()
                .loginPage("/auth").usernameParameter("login")
                .permitAll()
                .and()
                .logout().logoutSuccessUrl("/auth")
                .and().csrf().disable();
    }
}

控制器方法：

@RequestMapping(method = GET, value = "/auth")
    public String authorization() {
        return "Authorization";
    }

开始上课：

@SpringBootApplication
public class UquizApplication {

 public static void main(String[] args) {
  SpringApplication.run(UquizApplication.class, args);
 }
}

Answer 1

您将请求映射到“/auth”并访问请求“Authorization.jsp”。您的请求应该是 localhost:port/auth

Answer 2

请更正您的属性文件中的错字： spring.mvc.view.preffix 到 spring.mvc.view.prefix
