使用Springboot的MVC架构进行编写:
其中数据库操作部分使用mybatis自动生成基础代码,然后通过自己手写sql补充对应的缺失操作代码:
<?xml version="1.0" encoding="UTF-8"?>

<classPathEntry location="/Users/jiangyi/IdeaProjects/demo/src/main/resources/mysql-connector-java-8.0.27.jar"/>
<context id="DB2Tables" targetRuntime="MyBatis3">
<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"/>

<!--数据库链接URL,用户名、密码 -->

</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 生成模型的包名和位置-->
<javaModelGenerator targetPackage="com.example.demo.entity" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!-- 生成映射文件的包名和位置-->
<sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">

</sqlMapGenerator>
<!-- 生成DAO的包名和位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.example.demo.dao" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->
<!-- <table tableName="Sort_AOPEDF_protein_drug_score" domainObjectName="Sort_AOPEDF_protein_drug_score" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>-->
<!-- <table tableName="Sort_DeepDR_disease_drug_score" domainObjectName="Sort_DeepDR_disease_drug_score" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>-->
<!-- <table tableName="Sort_deepDTnet_protein_drug_score" domainObjectName="Sort_deepDTnet_protein_drug_score" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>-->
<table tableName="Sort_HetDR_disease_drug_score" domainObjectName="Sort_HetDR_disease_drug_score" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>
其中注释中的文字说明配置单中所要填写的配置信息。
Springboot在配置mybatis时需要加载的依赖文件:
如下方代码;
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

其中dependencies中的org.mybatis.generator是生成器的依赖,其配置文件在<plugin>中的config标签中配置。
在使用mybatis时需要的步骤:
1.在配置文件中,写好对需要自动生成表的名字类
<table tableName="Sort_HetDR_disease_drug_score" domainObjectName="Sort_HetDR_disease_drug_score" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
然后通过maven的包管理,自动运行mybatis的脚本文件。然后就自动生成了对应的文件。

2. 其中对应的生成文件中的标签如<Select>等,对应的是对数据库表的具体操作。
<?xml version="1.0" encoding="UTF-8" ?>

where C2 = #{C2}
</select>
<select id="selectByKey" resultMap="BaseResultMap" parameterType="java.lang.String">

</mapper>
最终搭建起来的框架可以在MVC架构的加持下,可以比较适合多人的代码编写,代码比较规范。
