SpringBoot + SSM環境搭建

springboot整合ssm非常容易，不需要再像普通ssm項目一樣配置一大堆xml文件，只需要配置非常少的文件 ，一起來看一看吧

創建maven項目，導入pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
         http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.itheima</groupId>
    <artifactId>springboot_ssm</artifactId>
    <version>1.0-SNAPSHOT</version>
    <!--打包方式-->
    <packaging>war</packaging>
    <!--jdk版本-->
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>
    <!--父工程坐標-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
    </parent>
    <dependencies>
        <!--web啟動器-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>

                </exclusion>
            </exclusions>
        </dependency>
        <!--日志-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-log4j2</artifactId>

        <!--jdbc-->

            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
        <!--mybatisplus啟動器-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.1.2</version>
        </dependency>
        <!--mysql-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.47</version>
        </dependency>
        <!--spring-test-->

            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
    </dependencies>
    <!--maven插件-->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

創建yaml文件

logging:
  level:
    cn.itcast: debug                #指定目錄的日志級別
    org.springframework: debug      #Spring框架日志級別 debug info warn error fatal
server:
  port: 80

#HikariCP數據源設置
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/saas-export?characterEncoding=utf-8
    username: root
    password: root

#mybatis-plus設置
mybatis-plus:
  mapper-locations: classpath:mapper/*.xml # mapper.xml文件位置,如果沒有映射文件，請注釋掉

創建啟動類

@SpringBootApplication
@MapperScan("com.itheima.mapper")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

其他文件和SSM一樣，這里不做贅述。
