Eclipse用maven构建SSM框架遇到的问题及解决方法
听说Maven很好用,刚刚好实验了Spring+Mvc企业应用实践的一个小项目,所以就拿它来练手了,用maven来重构它。
开发环境如下:
Eclipse:Eclipse Project Release Notes 4.7 (Oxygen)
JDK:JDK1.8.0_144
Maven:apache-maven-3.5.4
Tomcat:Tomcat 9
环境的配置就不多说了,其实只要有目录就行,Eclipse中配好就可以了
首先新建Maven项目,如果是第一次建Maven项目的话,一定要确保网络状态良好,因为任何下载中断或者下载错误都会导致创建Maven项目失败。
这里选webapp
创建完成就报错了,Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:1.0 from any of the configured repositories.可以看出是仓库的问题
原因是archetype错误,去maven仓库删掉它的最后更新文件,重新建就会再下了
创建成功,项目目录如下
先把jdk换一下,因为我之前改了maven的settings.xml,所以直接1.8了,不然是1.5
添加的语句如下
<profile>
<id>jdk-1.8</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.8</jdk>
</activation>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
</profile>
再添加tomcat9配置
看一下Project Facet,发现是Module版本是2.3
先不改,直接运行一下,成功了
在网上看了一些资料,说servlet和这个module是有对应版本的,还是把它改高一些把
再打开
再运行,tomcat报了错
再次运行,能成功进去了
接下来先改web.xml,因为改成3.1了,而web.xml里的声明还是2.3,直接删掉就行了
如果你不删会怎么样呢,我被这个错误弄了好久,哈哈Description Resource Path Location Type
Cannot change version of project facet Dynamic Web Module to 2.3. fkbookapp-maven line 1 Maven Java EE Configuration Problem
pom.xml添加一些依赖

Update一下,它会自动下载jar包到仓库
接下来修改建立SSM所需的配置文件,文件内容我上传到github上了https://github.com/Rambo55555/fkbookapp-maven
建立src/main/java目录存java文件
导入项目内容
结果:
哈哈哈,乌蝇哥
