千峰商城-springboot项目搭建-16-整合tkMapper

1.在fmmall项目的mapper子工程的pom中添加依赖：

<!--tkMapper-->
        <dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper-spring-boot-starter</artifactId>
            <version>2.1.5</version>
        </dependency>

2.在api子工程的ApiApplication中更改@MapperScan的important：import tk.mybatis.spring.annotation.MapperScan;

package com.qfedu.fmmall;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import tk.mybatis.spring.annotation.MapperScan;

@SpringBootApplication
@MapperScan("com.qfedu.fmmall.dao")
public class ApiApplication {

    public static void main(String[] args) {
        SpringApplication.run(ApiApplication.class, args);
    }

}

3.删除beans中的所有entity，mapper中的所有dao和mapper.xml。

4.在mapper子工程的pom文件中添加tkmapper插件和依赖。

    <build>
        <plugins>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.5</version>
                <configuration>
                    <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>8.0.28</version>
                    </dependency>
                    <dependency>
                        <groupId>tk.mybatis</groupId>
                        <artifactId>mapper</artifactId>
                        <version>4.1.5</version>
                    </dependency>
                </dependencies>
            </plugin>
        </plugins>
    </build>

5.在mapper子工程中添加配置：

<?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>
    <!-- 引入数据库连接配置 -->
    <!--    <properties resource="jdbc.properties"/>-->

    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        <!-- 配置 GeneralDAO -->
        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="com.qfedu.fmmall.general.GeneralDAO"/>
        </plugin>

        <!-- 配置数据库连接 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/fmmall2?useSSL=false"
                        userId="root" password="123456">
            <property name="nullCatalogMeansCurrent" value="true"/>
        </jdbcConnection>

        <!-- 配置实体类存放路径 -->
        <javaModelGenerator targetPackage="com.qfedu.fmmall.entity" targetProject="src/main/java"/>

        <!-- 配置 XML 存放路径 -->
        <sqlMapGenerator targetPackage="/" targetProject="src/main/resources/mappers"/>

        <!-- 配置 DAO 存放路径 -->
        <javaClientGenerator targetPackage="com.qfedu.fmmall.dao" targetProject="src/main/java" type="XMLMAPPER"/>

        <!-- 配置需要指定生成的数据库和表，% 代表所有表 -->
        <table tableName="%"></table>
    </context>
</generatorConfiguration>

6.添加插件的configuration。

                <configuration>
                    <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>

7.双击maven中的generator：generate。

生成成功！

8.将生成的所有entity移到beans子工程下的entity包中。

9.将原本在mapper子工程的pom中的tkmapper依赖转移到beans子工程中。刷新maven包。

<!--tkMapper-->
        <dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper-spring-boot-starter</artifactId>
            <version>2.1.5</version>
        </dependency>

10.在http://localhost:8080/doc.html中进行接口测试。
