一、创建maven父工程；
1、修改pom.xml，最终结果如下：
<?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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>cn.mauth</groupId> <artifactId>shop</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <modules> <module>shop-dao</module> <module>shop-service</module> <module>shop-model</module> </modules> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <kotlin.version>1.0.6</kotlin.version> </properties> </project>
二、创建springboot的api子工程；
1、修改application.properties文件，如下：
server.port=20190 spring.datasource.driver-class-name = com.mysql.jdbc.Driver spring.datasource.url = jdbc:mysql://localhost/shop_pro?useUnicode=true&characterEncoding=utf-8 spring.datasource.username = root spring.datasource.password = root
2、修改pom.xml文件，如下：
<?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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.8.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>cn.mauth</groupId> <artifactId>shop-api</artifactId> <version>0.0.1-SNAPSHOT</version> <name>shop-api</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.0</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.27</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>cn.mauth</groupId> <artifactId>shop-service</artifactId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> <resources> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> <include>**/*.tld</include> <include>**/*.jsp</include> </includes> <filtering>true</filtering> </resource> </resources> </build> </project>
3、修改主类ShopApplication，如下：
package cn.mauth.shop.api; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.ComponentScan; @SpringBootApplication @ComponentScan(basePackages = {"cn.mauth.shop.api","cn.mauth.shop.service"}) @MapperScan("cn.mauth.shop.dao") public class ShopApiApplication { public static void main(String[] args) { SpringApplication.run(ShopApiApplication.class, args); } }
三、创建maven的dao子工程；
1、配置mybatis逆向工程，修改pom.xml文件，如下：
<?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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>shop</artifactId> <groupId>cn.mauth</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <groupId>cn.mauth</groupId> <artifactId>shop-dao</artifactId> <dependencies> <!--防止找不到驱动 导致异常： Exception getting JDBC Driver--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.27</version> </dependency> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.4</version> </dependency> <dependency> <groupId>cn.mauth</groupId> <artifactId>shop-model</artifactId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies> <build> <resources> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> <include>**/*.tld</include> <include>**/*.jsp</include> </includes> <filtering>true</filtering> </resource> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> <include>**/*.tld</include> </includes> <filtering>true</filtering> </resource> </resources> <plugins> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <configuration> <configurationFile>src/main/resources/generator_config.xml</configurationFile> <verbose>true</verbose> <overwrite>true</overwrite> </configuration> <executions> <execution> <id>Generate MyBatis Artifacts</id> <goals> <goal>generate</goal> </goals> </execution> </executions> <dependencies> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.27</version> </dependency> </dependencies> </plugin> </plugins> </build> </project>
2、新增generator_config.xml文件在resources目录下，如下：
<?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="test" targetRuntime="MyBatis3"> <plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"></plugin> <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin> <plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin> <commentGenerator> <!-- 这个元素用来去除指定生成的注释中是否包含生成的日期 false:表示保护 --> <!-- 如果生成日期，会造成即使修改一个字段，整个实体类所有属性都会发生变化，不利于版本控制，所以设置为true --> <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> <!--数据库链接URL，用户名、密码 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/shop_pro?serverTimezone=Asia/Shanghai" userId="root" password="root"> </jdbcConnection> <javaTypeResolver> <!-- This property is used to specify whether MyBatis Generator should force the use of java.math.BigDecimal for DECIMAL and NUMERIC fields, --> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- 生成模型的包名和位置 --> <javaModelGenerator targetPackage="cn.mauth.shop.model" targetProject="../shop-model/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="cn.mauth.shop.dao" targetProject="src/main/java"> <property name="enableSubPackages" value="true" /> </sqlMapGenerator> <!-- 生成DAO的包名和位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="cn.mauth.shop.dao" targetProject="src/main/java"> <property name="enableSubPackages" value="true" /> </javaClientGenerator> <!-- 要生成哪些表 --> <!--<table tableName="SYS_USER"></table>--> </context> </generatorConfiguration>
3、逆向生成model、mapper和mapper.xml
四、创建maven的model子工程；
五、创建maven的service子工程；
1、新增service，如下：
package cn.mauth.shop.service;
import cn.mauth.shop.dao.SysUserMapper;
import cn.mauth.shop.model.SysUser;
import cn.mauth.shop.model.SysUserExample;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class SysUserService {
@Autowired
public SysUserMapper sysUserMapper;
//查询所有用户
public List<SysUser> selectAll(){
SysUserExample sue = new SysUserExample();
sue.createCriteria().andIsDelEqualTo("0");
List<SysUser> sysUserList = sysUserMapper.selectByExample(sue);
return sysUserList;
}
}
2、新增controller，如下：
package cn.mauth.shop.api.controller; import cn.mauth.shop.service.SysUserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import java.util.List; @Controller public class SysUserController { @Autowired public SysUserService sysUserService; @RequestMapping(value = "/admin/getAllSysUser",method = RequestMethod.GET) @ResponseBody public List getAllSysUser(){ List list = sysUserService.selectAll(); return list; } }
3、修改pom.xml文件，如下：
<?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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>shop</artifactId> <groupId>cn.mauth</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <groupId>cn.mauth</groupId> <artifactId>shop-service</artifactId> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>5.1.9.RELEASE</version> </dependency> <dependency> <groupId>cn.mauth</groupId> <artifactId>shop-dao</artifactId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies> </project>
六、启动项目，输入http://localhost:20190/admin/getAllSysUser访问本地服务器
测试成功。
