@SpringBoot访问jsp页面报404错误

SpringBoot访问jsp页面报404错误

1、在pom.xml文件增加对应的jar包

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>
        <!-- Tomcat的支持 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
</dependency>

在build标签增加

<resources>
            <resource>
                <directory>src/main/webapp</directory>
                <targetPath>META-INF/resources</targetPath>
                <includes>
                    <include>**/**</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
                <includes>
                    <include>**/**</include>
                </includes>
            </resource>
</resources>

2、修改配置文件增加

#spring mvc 配置
spring.mvc.view.prefix=/WEB-INF/
spring.mvc.view.suffix=.jsp

或者增加

package com.unicom.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@Configuration
public class MyConfigurer extends WebMvcConfigurerAdapter {

    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/");
        viewResolver.setSuffix(".jsp");
        viewResolver.setViewClass(JstlView.class);
        return viewResolver;
    }
}

3、如果以上方法还是不行，那就是工作目录的问题。修改工作目录方式如下：

修改箭头所指的为当前内容即可。如何没有该选项，maven clean 和 compile 完毕即可看到该内容。
