JSP和Spring启动时出现意外错误（404未找到）

Question

当我试图将一个项目翻译成Spring Boot时，我遇到了一个错误——我无法理解我做错了什么。将后缀和前缀添加到属性文件中，试图更改jsp的位置，debager显示在控制器的方法中。我做错了什么？如果有任何帮助，我将不胜感激

错误：

此应用程序没有针对/错误的显式映射，因此您将其视为回退。

Spring Boot应用程序。属性：

logging.level.root = info

spring.mvc.view.preffix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

spring.datasource.url=jdbc:mysql://localhost:3306/quizzes?autoReconnect=true&useSSL=false
spring.datasource.username=root
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=none
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate5.SpringSessionContext

Sping安全配置：（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”，然后访问请求“Authorization.jsp”。您的请求应该是localhost:port/auth

Answer 2

请更正属性文件中的输入错误：spring。mvc。看法预固定到Spring。mvc。看法前缀
