Maven整合SSH框架的所有依赖和插件（记录下来，省的以后再写）

JDK：1.8

Tomcat：7

Maven：3.6.1

　　调了一个小时，终于没错误了，总结了一个规律，如果在用Tomcat插件启动项目时报错，显示如：org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 19的错误时，多半是因为导入的依赖版本太高了，看错误信息是什么，根据错误信息把相应的依赖版本改低就行，还有可能是项目运行和编译的JDK版本没统一，建议把Maven编译时JDK版本改成和自己装的JDK版本一致，如下所示（我的是1.8）：

<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.6.1</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
</plugin>
