Spring Boot配置

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

        <resources>
            <resource>
                <directory>src/main/javadirectory>
                <includes>
                    <include>**/*.xmlinclude>
                includes>
            resource>
        resources>

###2、maven一些常用的配置包

		
        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
            <scope>runtimescope>
        dependency>
		
        <dependency>
            <groupId>org.projectlombokgroupId>
            <artifactId>lombokartifactId>
            <optional>trueoptional>
        dependency>
		
        <dependency>
            <groupId>org.mybatis.spring.bootgroupId>
            <artifactId>mybatis-spring-boot-starterartifactId>
            <version>2.2.2version>
        dependency>
        
        <dependency>
            <groupId>org.mybatis.generatorgroupId>
            <artifactId>mybatis-generator-coreartifactId>
            <version>1.4.0version>
        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
