• 【IDEA】使用Maven骨架创建JavaWeb项目


    IDEA版本:2020.1

    骨架选项名称:

    org.apache.maven.archetypes:maven-archetype-webapp

    本项目的Maven坐标设置:

    设置优先从本地获取骨架:

    archetypeCatalog=internal

    构建过程的控制台打印:

    目录结构:

    发现我们的源码包和资源包都没有配置,只有一个放置页面资源的webapp目录

    我们可以把webapp拖动放到我们想存放的位置:

    自己手动配置Resource和Java目录

    在对main目录进行右键创建包的时候,IDEA会自动建议创建Maven项目的目录结构

    JSP首页甚至没有JSP指令标签。。。

    <html>
    <body>
    <h2>Hello World!</h2>
    </body>
    </html>

    可以把POM配置这些都更新:

      <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
      </properties>
    
      <dependencies>
        <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>4.13</version>
          <scope>test</scope>
        </dependency>
      </dependencies>

    也就是说这个骨架最初并不是给IDEA创建的

    而是给Eclipse使用的。。。

    接下来是配置Tomcat

    点加号找到TomcatServer选择本地,千万别下面的EE Server

    IDEA会提示你还没有配置Tomcat,直接Fix就好了

    选下面这个explored的

    自行更换工程资源路径:

    重要的热部署选上:

    启动项目发现404,结果之前好好的webapp目录IDEA不识别了

    因为默认的配置路径IDEA找不到了,需要我们自己改上去:

    把之前的index.jsp删除,重新配置一个
