Spring Boot配置

###1、Mybatis映射

​ xx.xml的mybatis映射不会自动打包到target需要在build中导入配置

<!--将mybatis的xml映射文件一起进行打包-->
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>

###2、maven一些常用的配置包

		<!-- mysql依赖 -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>
		<!--懒人封装-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
		<!--mybatis依赖-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.2.2</version>
        </dependency>
        <!-- mybatis自动生产功能需要的依赖-->
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.4.0</version>
        </dependency>

###3、application配置

spring.datasource.url=jdbc:mysql://xxxxxxxx:3306/xxxx?serverTimezone=GMT%2B8
spring.datasource.username=xxxxx
spring.datasource.password=xxxxxx
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

4、当有多个mapper文件时

​ 在spring boot启动文件中加入

@MapperScan("com.ant.demo.Mapper")//当不止一个mapper文件时会找不到mapper文件需要映射

###5、controller中加入跨域

@CrossOrigin

6、controller标记

@RestController//标记此层为controller
