使用IDEA快速搭建SSM+SpringBoot项目

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用IDEA快速搭建SSM+SpringBoot项目相关的知识，希望对你有一定的参考价值。
1.创建包
一般项目必不可少的包有、controller（控制器）、mapper（接口）、pojo（实体类）、service（接口的实现类）、util（工具类），注意准守规范，包名全小写！
resources目录下需创建mapper包，用于与数据库交互
在main下面创建webapp包，用于放一些资源文件，如static、WEB-INF中的jsp、lib等等
2.配置SpringBoot启动类
代码如下：
package com.apollo.apollodemo; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.ServletComponentScan; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; /** * SpringBoot启动类 */ @SpringBootApplication @ServletComponentScan @MapperScan("com.apollo.apollodemo.mapper") //@MapperScan 用户扫描MyBatis的Mapper接口 public class Apollo extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(Apollo.class); } public static void main(String[] args) { SpringApplication.run(Apollo.class, args); } }
3.pom文件导入常用的包（这里需要配置好Maven仓库）
自行参考
<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.7.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.apollo</groupId> <artifactId>apollodemo</artifactId> <version>0.0.1-SNAPSHOT</version> <!--改为war方式--> <packaging>war</packaging> <name>apollodemo</name> <description>Demo project for Spring Boot</description> <!-- jdk1.8 --> <properties> <java.version>1.8</java.version> </properties> <dependencies> <!-- springBoot的启动器 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- jasper --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> <!-- test --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> <!-- jstl --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency> <!-- log4j --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- Mybatis启动器 --> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.1.1</version> </dependency> <!-- mysql数据库驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- druid数据库连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.9</version> </dependency> <!-- 热部署 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> </dependency> <!-- Lombok --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.8</version> <scope>provided</scope> </dependency> <!-- alibaba-fastjson --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.35</version> </dependency> <!--poi --> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.17</version> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-core</artifactId> <version>4.0.8</version> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-dysmsapi</artifactId> <version>1.1.0</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>3.17</version> </dependency> <!-- easyexcel --> <dependency> <groupId>com.alibaba</groupId> <artifactId>easyexcel</artifactId> <version>1.1.2-beta5</version> </dependency> <dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.4</version> <classifier>jdk15</classifier> <exclusions> <exclusion> <groupId>commons-collections</groupId> <artifactId>commons-collections</artifactId> </exclusion> <exclusion> <groupId>commons-lang</groupId> <artifactId>commons-lang</artifactId> </exclusion> <exclusion> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>commons-lang</groupId> <artifactId>commons-lang</artifactId> <version>2.6</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-io</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>com.aliyun.oss</groupId> <artifactId>aliyun-sdk-oss</artifactId> <version>2.5.0</version> </dependency> <dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.4</version> <classifier>jdk15</classifier> </dependency> <!--打包的时候可以不用包进去，别的设施会提供。事实上该依赖理论上可以参与编译，测试，运行等周期。 相当于compile，但是打包阶段做了exclude操作 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
4.项目全局配置文件application.properties（这里也可以改成其它格式的文件）
#配置端口号
server.port=88
#配置MYSQL数据库
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://数据库链接/数据库名称?characterEncoding=utf-8&useSSL=false&allowMultiQueries=true
spring.datasource.username=******
spring.datasource.password=******
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
#配置控制器返回路径
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
mybatis.type-aliases-package=com.apollo.appllodemo.pojo
mybatis.mapper-locations=classpath:mapper/*.xml
#配置时间格式
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8
spring.jackson.serialization.write-dates-as-timestamps=false
#配置日志文件
logging.level.com.muen.mapper=debug
