(4)Maven快速入门_4在Spring+SpringMVC+MyBatis+Oracle+Maven框架整合运行在Tomcat8中

利用Maven 创建Spring+SpringMVC+MyBatis+Oracle 项目

分了三个项目  Dao   (jar)   Service (jar)   Controller (web)

工程下载地址：https://pan.baidu.com/s/1Q9I6V9Mlw47Eua18N9do3Q 密码 1kbs

遇到的几个坑：

1、oracle 的数据库连接jar  Maven库中不存在！！！

Missing artifact com.oracle:ojdbc6 :jar:11.2.0

需要手动下载ojdbc  然后编译安装到本地maven仓库 ：Windows(7) 系统运行 cmd 打开 DOS 窗口，进入 Oracle JDBC 驱动包所在的目录，执行命令

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2. -Dpackaging=jar -Dfile=ojdbc6.jar

参考解决此问题的文章地址：Missing artifact com.oracle:ojdbc14:jar:10.2.0.4.0 解决方案

如果还报 驱动找不到

Could not
load JDBC driver class [oracle.jdbc.OracleDriver]

则直接把 ojdbc6.jar 直接放到tomcat的lib目录下。

2、*mapper.xml 等配置文件通常情况下要放在  src/main/resources目录下（推荐）！！！

如果*mapper.xml 是放在 src/main/java 目录下 则有时会出现 找不到xml文件的的情况，

for property 'mapperLocations'; nested exception is java.lang.IllegalArgumentException: Could not resolve resource

出现上述错误的主要原因在于 maven 并不会自动将 src/main/java 中的 xml 等资源文佳复制到 target/classes 中去，

，需要在pom.xml中 添加如下信息

 <build>
        <resources>
<!--             编译之后包含xml -->
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
<!--             编译之后包含xml -->
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>

参考解决此问题的文章地址：maven项目无法打包编辑mapper下的xml文件

以上是利用Spring4+SpringMvc+mybatis+maven+Oracle 分项目搭建框架过程中遇到的坑。

下面贴出搭建过程:

1、dao 项目创建：

在eclipse中 new --->other--->maven ---->maven project 如下图：

next 如下图

next ，普通Java项目  选择quickstart  标红一项；javaweb项目 选择 webapp标红一项。此处是普通java项目 选择第一项。

next之后填写 Group Id   、Artifact Id 、Version（默认即可）   这三个参数组成了 Maven中 定位一个jar的坐标。

finish创建的项目，目录结构如下：

src/main/java

src/test/java

src/main/resources

pom.xml

打开pom.xml 注释以下标注内容

上述四个文件作用 可参考  (3)Maven快速入门_3在Eclipse中创建Maven项目打包成jar

此处说明下：  main 目录下创建  dao和 entity的 package  对应的存放*Mapper.xml的mappers 的package需要放在resources目录下（推荐）  。如果 mappers的package放在 main下 dao 和 entity同一目录下 ，则 需要注意解决一下上文提到的mapper.xml找不到错误的问题。

pom.xml 内容：

log4j  、ojdbc 、mybatis的  maven 插件jar包。注：ojdbc一定要安装到本地maven仓库，否则即使在 pom.xml中引入ojdbc   maven依赖中也没有 ojdbc.jar

t_user表的sql语句

-- Create table
create table T_USER
(
  id       NUMBER,
  username NVARCHAR2(100),
  password NVARCHAR2(100)
)

右键点击 pom.xml  ---- Run As---- maven install  在target和本地仓库中生成  jar    target目录中,生成内容如下：

右键点击 pom.xml  ---- Run As---- maven clean   在target和本地仓库中清理 已经生成  jar ，重新执行 maven  install  可再次生成jar

2、创建 service 项目  与dao项目创建的方式相同 ，只贴代码

项目结构如下：

pom.xml文件内容:

spring4 的maven依赖包， spring4 与mybatis集成的的maven依赖包 。

注：依赖dao项目 需要添加 dao项目的 maven信息 ， 可从dao项目 pom.xml的中复制 groupid  artifactId version  信息。

依然需要 点击 pom.xml 右键执行 Run As  执行 maven  install 在target目录 和本地maven仓库生成 jar

3、controller 项目 （web）

此处需要创建maven版本的 web项目 ：选择 -webapp

项目结构如下：

此处比maven普通的java项目需要多web项目结构的信息 都存放在src/main/webapp下

pom.xml文件：

jsp 、servlet 、jstl、Springmvc 的 maven插件支持   还需要引入 service项目 (service项目中已经引入dao了， 所以不需要单独引入dao)。

引入之后maven插件中就会有service和dao项目
