一、创建maven项目
二、在pom添加spring boot相关的jar包
1、完善maven项目
添加<packaging>jar</packaging>
<name>Demo</name>
<description>Demo project for Spring Boot</description>
2、实现spring boot
2.1、基础jar包引入
实现spring boot有多种形式，一种是继承父类中的spring boot
如下：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.2.RELEASE</version>
<relativePath />
</parent>
还有一种是直接添加：
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.0.2.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
2.2、配置UTF-8编码格式
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
2.3、spring boot jar包引入
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
以上配置完以后基础的框架已经配置好了。
三、pom文件集成mybaties-plus jar包
1、加入mysql包
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.6</version>
</dependency>
2、加入mybaties-plus jar包
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatisplus-spring-boot-starter</artifactId>
<version>1.0.5</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus</artifactId>
<version>2.3</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
spring boot如果是2.0版本以上的mybatis-plus建议用最新版本的目前我在用的是2.3版本亲测可用。
如果是低版本的会出现版本出现出图问题。
3、加入生成代码工具的jar 包
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity</artifactId>
<version>1.7</version>
</dependency>
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.28</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.velocity/velocity-engine-core -->
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity-engine-core</artifactId>
<version>2.0</version>
</dependency>
四、 pom文件配置部署环境
<build>
<resources>
<resource>
<directory>src/main/java</directory>
<filtering>false</filtering>
<includes>
<include>*/.xml</include>
</includes>
</resource>
<resource>
<directory>src/main/resources</directory>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
五、配置文件中设置
1、服务设置
server.port=8080
2、#DRUID POOL 配置
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
spring.datasource.maxWait=60000
spring.datasource.timeBetweenEvictionRunsMillis=60000
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
spring.datasource.filters=stat,wall,log4j
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
3、#Default DataBase Source
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.url=
spring.datasource.username=
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
4、#mybatis-plus
在resource路径下的mybatis文件夹
mybatis-plus.mapper-locations=classpath\:mybatis/*Mapper.xml
扫描model的文件
mybatis-plus.typeAliasesPackage=com.java.model
mybatis-plus.global-config.id-type=2
mybatis-plus.global-config.field-strategy=2
mybatis-plus.global-config.auto-set-db-type=true
mybatis-plus.global-config.db-column-underline=true
mybatis-plus.global-config.refresh-mapper=true
mybatis-plus.configuration.map-underscore-to-camel-case=true
mybatis-plus.configuration.cache-enabled=false
5、#log4j
log4j.rootLogger=info,ServerDailyRollingFile,stdout
log4j.appender.ServerDailyRollingFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ServerDailyRollingFile.DatePattern='.'yyyy-MM-dd
log4j.appender.ServerDailyRollingFile.File=D://test/test.log
log4j.appender.ServerDailyRollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.ServerDailyRollingFile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p [%c] - %m%n
log4j.appender.ServerDailyRollingFile.Append=true
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d yyyy-MM-dd HH:mm:ss %p [%c] %m%n
六、代码生成器
请参考官网
七、代码配置mybatis-plus
@Configuration
@MapperScan("com.java.mapper*")
public class MybatisPlusConfig {
/**
* mybatis-plus分页插件<br>
* 文档：http://mp.baomidou.com<br>
*/
@Bean
public PaginationInterceptor paginationInterceptor() {
PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
paginationInterceptor.setDialectType(DBType.MYSQL.getDb());
return paginationInterceptor;
}
}
