springBoot

pom依赖

 

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
        <relativePath/>
    </parent>

  <dependencies>
          <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
  </dependencies>　

修改springBoot的Tomcat端口：

在src/main/resource下新建application.properties配置文件，在文件中添加server.port=8081

即可把tomcat端口修改为8081。

新建的resource需要设置为source目录，(eclipse)Build Path/Use As Source Folder。设置完后启动即可

如需整合mybatis，pom.xml中添加

        <!-- mysql-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.21</version>
        </dependency>

        <!-- mybatis -->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.1.1</version>
        </dependency>

application.properties添加

spring.datasource.url=jdbc:mysql://localhost:3306/testshop?characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=lin000
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

mybatis.mapper-locations=classpath:mapper/*.xml

 

resources路径下新建mapper文件夹保存xml文件，启动类添加注解@MapperScan("Dao接口的包名")或者在Dao层的类中添加@Mapper，如果不添加就会启动失败，Dao层没有放到容器中，不能使用@Autowired进行注入。会出现这种错误

Field xxx in xxxxxxxxxxx required a bean of type 'xxxxxxxxxDao' that could not be found.

Consider defining a bean of type 'xxxxxxxxxxxDao' in your configuration.

如果使用了@MapperScan后还是出现错误，就看下xml的配置文件是否有错误
