New springboot + mybatis plus project

First, use idea to create a new SpringBoot

In this way, a spring boot project is created. Here is the new project structure

Add mybatis plus and other dependencies to the pom.xml file

Add project configuration in the application.properties file

#Configure port number server.port = 8888 #Load driver spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver #Database connection path spring.datasource.url=jdbc:mysql://localhost:3306/mp?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC #Database user name spring.datasource.username=root #Database password spring.datasource.password=123456 #Data source type (Alibaba) spring.datasource.type=com.alibaba.druid.pool.DruidDataSource #Configuration log (showing SQL statements executed by mybatis) logging.level.com.example.demo.mapper=debug

Create a new controller, entity, mapper and service layer

Load mybatis in the startup class

@SpringBootApplication // Load mybatis @MapperScan("com.example.demo.mapper") public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }

Add code generation class

/** * Code generation class */ public class GenMain { /** * <p> * Read console content * </p> */ public static String scanner(String tip) { Scanner scanner = new Scanner(System.in); StringBuilder help = new StringBuilder(); help.append("Please input" + tip + ": "); System.out.println(help.toString()); if (scanner.hasNext()) { String ipt = scanner.next(); if (StringUtils.isNotEmpty(ipt)) { return ipt; } } throw new MybatisPlusException("Please enter the correct" + tip + "!"); } public static void main(String[] args) { // Code generator AutoGenerator mpg = new AutoGenerator(); // Global configuration GlobalConfig gc = new GlobalConfig(); String projectPath = System.getProperty("user.dir"); gc.setOutputDir(projectPath + "/src/main/java"); gc.setAuthor("gzh"); gc.setOpen(true); // gc.setSwagger2(true); entity attribute Swagger2 annotation mpg.setGlobalConfig(gc); // Data source configuration DataSourceConfig dsc = new DataSourceConfig(); // Oracle path // dsc.setUrl("jdbc:oracle:thin:@localhost:1521:orcl"); dsc.setUrl("jdbc:mysql://localhost:3306/mp?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC"); // dsc.setSchemaName("public"); dsc.setDriverName("com.mysql.cj.jdbc.Driver"); dsc.setUsername("root"); dsc.setPassword("123456"); mpg.setDataSource(dsc); // Packet configuration PackageConfig pc = new PackageConfig(); pc.setModuleName(scanner("Module name")); pc.setParent("com.example"); mpg.setPackageInfo(pc); // Custom configuration InjectionConfig cfg = new InjectionConfig() { @Override public void initMap() { // to do nothing } }; // If the template engine is freemarker String templatePath = "/templates/mapper.xml.ftl"; // If the template engine is velocity // String templatePath = "/templates/mapper.xml.vm"; // Custom output configuration List<FileOutConfig> focList = new ArrayList<>(); // Custom configuration will be output first focList.add(new FileOutConfig(templatePath) { @Override public String outputFile(TableInfo tableInfo) { // Customize the output file name.

At this point, the project of springboot + mybatis plus is completed.
