朴灿烈づ我的快乐病毒、 2022-05-17 11:22 193阅读 0赞

需求表均同springmvc案例

此处只是使用maven

注意,以下所有需要建立在你的eclipse等已经集成配置好了maven了,说白了就是新建项目的时候已经可以找到maven了

没有的话需要安装maven

1.新建maven项目,如果不在上面,请到other里面去找一下

2,进入maven项目之后,点击next

[![b7f2746f-bd7f-4120-9f72-ffb4d6f333d5][]][b7f2746f-bd7f-4120-9f72-ffb4d6f333d5 1]

选择webapp之后  next

输入两个id  package可以不写,是它默认帮你新建一个包,不写没关系

会生成一个这样目录的项目

[![82370fe2-eeb0-4329-8f64-6211ef44b515][]][82370fe2-eeb0-4329-8f64-6211ef44b515 1]

2,配置maven

首先新建几个文件夹

2.1 添加Source文件夹

接下来需要添加

src/main/java

src/test/java

src/test/resources三个文件夹

右键项目根目录点击New -> Source Folder，

建出这三个文件夹。注意不是建普通的Folder，而是**Source Folder**。

项目或者文件加上右键 new  sourceFolder,正常情况下是没有问题的

**如果出现了下面的这情况,其实是真的存在的只是我们看不到**

[![c11f0c74-6f2c-48d0-b670-fc8732a6e370][]][c11f0c74-6f2c-48d0-b670-fc8732a6e370 1]

项目右键属性

[![5eca2484-567c-4ecc-a60b-8fb8fb3b45d2][]][5eca2484-567c-4ecc-a60b-8fb8fb3b45d2 1]

[![c60b4c7b-e90d-497d-87b0-71fa4864e1e4][]][c60b4c7b-e90d-497d-87b0-71fa4864e1e4 1]

[![9f47bd00-72d1-4250-b9f3-ce71821f5630][]][9f47bd00-72d1-4250-b9f3-ce71821f5630 1]

切换成这样子就好了

[![c2683bbe-2e10-4570-abb8-12fc4efe1223][]][c2683bbe-2e10-4570-abb8-12fc4efe1223 1]

设置好了之后发现

[![9fa41717-c27a-4427-abd6-c991dfd22e82][]][9fa41717-c27a-4427-abd6-c991dfd22e82 1]

java就已经有了

继续新建其他的几个还没有的

新建之后就这样子了

[![644111c7-352f-43b2-a5cf-d5080783e1ae][]][644111c7-352f-43b2-a5cf-d5080783e1ae 1]

2.2 更改class路径

右键项目，Java Build Path -> Source

下面应该有4个文件夹。src/main/java，src/main/resources，src/test/java ，src/test/resources。

双击每个文件夹的Output folder，选择路径。

src/main/java，src/main/resources，选择target/classes;

src/test/java ，src/test/resources, 选择target/test-classes;

选上Allow output folders for source folders.（如果没有选上的话）

[![85d08a77-0e84-4c7e-be6f-4cdd3a8225d8][]][85d08a77-0e84-4c7e-be6f-4cdd3a8225d8 1]

此处还可以更改显示顺序

[![f12e377c-1453-40e1-b8d6-bf589b0a3d47][]][f12e377c-1453-40e1-b8d6-bf589b0a3d47 1]

此处还可以更改jdk

[![f69a61ed-0a5f-4967-9b11-ffa5817b4930][]][f69a61ed-0a5f-4967-9b11-ffa5817b4930 1]

右键属性  project Facets

想要切换成3.0发现报错

[![48282720-4b81-4e40-9f1c-8d7e51e153f1][]][48282720-4b81-4e40-9f1c-8d7e51e153f1 1]

这是因为新建项目的时候

用了maven-artchetype-webapp

由于这个catalog比较老，用的servlet还是2.3的

重新打开属性 project Facets,看到这个地方已经修改成3.0; 勾选上tomcat

项目工程创建完成

new 一个server

启动之后看看有无报错,目前没有

运行一下,测试没问题,至此maven  web项目创建完成
