打开Eclipse，在 ![20191105231823931.png][] 空白处右键 New 选择 Other

搜索 Maven ，点击 Maven Project 创建 Maven 项目

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 1][]

这里 Next 下一步即可

此处注意选这个，因为要创建web项目

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 3][]

Group Id 表示的是包名，Artifact Id 表示的是项目名

Finish 之后就是这样子啦，一堆问题。

### 解决冲突 ###

**第一步：**首先是，新建的maven项目只有 src/main/resouces 文件夹而没有 src/main/java 和 src/test/java 文件夹。自己新建的文件夹却没用，原因是其实项目本来有文件夹只是隐藏了，重新配置下即可。

右键项目->properties->java buildPath->选择原本的1.5版本然后remove，之后Add library->JRE SYSTEM Library，这边记得选择Alternate JRE。

**第二步：修改 web.xml 文件**

![20191107120327969.png][]

新创建的web.xml文件默认写的是2.3版本Dynamic Web Module 2.3这个版本默认匹配jdk1.5的，如果项目引入的是jdk1.7以上一般需要匹配2.5以上这里就需要调整了，我这里调整的是3.0。下面是配置代码 ：

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                            http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
                            version="3.0">
        <display-name>Archetype Created Web Application</display-name>
    </web-app>

接着右键项目->properties->Resource 查看项目路径找到 .setting文件夹的org.eclipse.wst.common.project.facet.core.xml

将2.3改成3.0

重启 Eclipse。

第三步：右键项目 --> properties --> Java Build Path将 tomcat 的 jar 包加上去

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 10][]

弄完之后看到 problem 还是有错误，不急，咱们继续解决。

**第四步：解决 pom.xml 中maven依赖包下载失败的问题**

[https://blog.csdn.net/Alone\_in\_/article/details/102955699][https_blog.csdn.net_Alone_in_article_details_102955699]（解决步骤在这篇博客里了）

**第五步：解决spring的jar包下载后不可用的问题**

在 pom.xm 中换个版本号4.3.9，保存后，右键项目 --- Maven --- Update Project Configuration。这次什么都不用改，直接OK等他更新完成就可以了。到目前，已经没有错误了。本来想着

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0Fsb25lX2luXw_size_16_color_FFFFFF_t_70 12][]

告一段落先。
