idea导入ssm项目启动tomcat报错404

用idea写ssm项目，基于之前一直在用spring boot 对于idea如何运行ssm花费了一番功夫

启动Tom act一直在报404 我搜了网上各种解决办法都不行，花费一天多的时间解决不了

就是在pom中添加下面代码

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.5.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                    <include>**/*.ini</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
    </build>

idea不配置各种文件，自己识别不了需要给指定

配置tomcat以及jdk

首先配置jdk
