springBoot+mybatis+thymeleaf+oracle+maven搭建web项目

我用的开发是IDEA，所以首先建立spring-boot项目，这个在spring-boot中很简单

这是完成搭建后的目录结构,后面如果我说的文件不知道放在哪，可以返回看看

1.引入thymeleaf：在maven中pom.xml 中加入依赖

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

在applcation.yml（application.properties改变格式就行（百度））中加入：

spring:
  #thymeleaf模板配置
  #热部署文件，页面不产生缓存，及时更新
  thymeleaf:
    prefix: classpath:/templates/
    suffix: .html
    mode: HTML5
    encoding: UTF-8
    cache: false
  resources:
    chain:
      strategy:
        content:
          enabled: true
          paths: /**

2.引入oracle：首先因为版权等原因，Oracle是不能像mysql那样直接在maven中添加的！所以我采用自己下驱动的方法（当然也可以用自己安装的Oracle里面有驱动）首先oracle的ojbc.jar（我的jar上传了）。第一步：在命令界面添加命令：

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.2.0 -Dpackaging=jar -Dfile=D:\app\ojdbc6-11.2.0.2.0.jar

注意：红色的地方就是你下的jar包的名字、版本和你放的地址。这个要匹配

如果显示bulid success就证明本地安装成功。然后就在pom.xml中添加

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc6</artifactId>
    <version>11.2.0.2.0</version>
</dependency>

这样就不会报红了。

3.引入mybatis：我采用的是mybatis mybatis-generator 代码自动生成工具（自动生成mapper.xml、dao、实体类）。maven添加依赖（加在<build><plugins> </plugins></build>里面）

<!-- mybatis generator 自动生成代码插件 -->
<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.2</version>
    <dependencies>
        <dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc6</artifactId>
            <version>11.2.0.2.0</version>
        </dependency>
    </dependencies>
    <configuration>
        <overwrite>true</overwrite>
    </configuration>
</plugin>
<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.2</version>
    <configuration>
        <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>
        <overwrite>true</overwrite>
        <verbose>true</verbose>
    </configuration>
</plugin>

然后按照这个弄：edit configuration

填好就可以apply后点ok。

然后在resources文件夹中添加自动生成文件的配置文件：generatorConfig.xml  （填写你的oracle地址，用户名密码，然后生成规则，按照文件夹的命名来改，红色是你自己的东西）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>

    <context id="oraclegenerator" targetRuntime="MyBatis3Simple">

        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <jdbcConnection driverClass="oracle.jdbc.OracleDriver"
                        connectionURL="jdbc:oracle:thin:@133.32.62.110:1521:UDPL"
                        userId="****"
                        password="****"/>

        <!--生成实体类-->
        <javaModelGenerator targetPackage="com.hrmanage.domain" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!--生成xml映射文件存放位置-->
        <sqlMapGenerator targetPackage="com.hrmanage.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>

        <!--生成dao类-->
        <javaClientGenerator targetPackage="com.hrmanage.dao" type="XMLMAPPER" targetProject="src/main/java">
            <!-- 在targetPackage的基础上，根据数据库的schema再生成一层package，最终生成的类放在这个package下，默认为false -->
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>

        <!--需要产生实体类的表-->
        <table schema="" tableName="CADRE_EXAMINATION_APPROVAL" domainObjectName="CadreInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
            <!-- 主键生成方式 -->
            <!--<generatedKey column="id" sqlStatement="select seq_t_user.nextval from dual" identity="true" />-->
            <!-- 列名去除前缀 -->
            <!--<columnRenamingRule searchString="^[^_]+" replaceString="" />-->
        </table>
    </context>
</generatorConfiguration>

配置完后选中运行，运行成功就会生成文件，如果没成功，请检查配置，或者去百度mybatis-generator用法。

mybatis还没完。还要配置一些东西，不然后面运行要报错。参考这个（同一项目）：
