Spring-boot整合mybatis-plus 2.3

pom文件需要添加的依赖:

	<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>2.3</version>
        </dependency>
        <!-- velocity 依赖，用于代码生成 -->
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.0</version>
        </dependency>

xml文件放在了resource根目录下
application.properties配置文件添加xml和实体类扫描:

mybatis-plus.mapper-locations=classpath:/mybatis/*.xml
mybatis-plus.typeAliasesPackage=cn.com.polycis.entity
//数据库字段下划线转驼峰
mybatis-plus.configuration.map-underscore-to-camel-case=true

MybatisPlusConfig配置文件:

import com.baomidou.mybatisplus.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
//扫描dao或者是Mapper接口
@MapperScan("cn.com.polycis.mapper*")
public class MybatisPlusConfig {
    /**
     * mybatis-plus 分页插件
     */

    @Bean
    public PaginationInterceptor paginationInterceptor() {

        PaginationInterceptor page = new PaginationInterceptor();
        page.setLocalPage(true);// 开启 PageHelper 的支持
        page.setDialectType("mysql");
        return page;
    }

}

启动类需要添加mapper扫描注解

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.PropertySource;

@PropertySource("application.properties")
@MapperScan("cn.com.polycis.mapper")
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
public class OtaApplication {
	public static void main(String[] args) {
		SpringApplication.run(OtaApplication.class, args);
	}
}
