之前使用springMVC+spring+mybatis,总是被一些繁琐的xml配置,有时候如果配置出错,还要检查各种xml配置,偶然接触到了spring boot 后发现搭建一个web项目真的是1分钟的事情,再也不用去管那么多xml配置,简直神清气爽,不用看那么多一坨xml,下面是我把以前的一些ssm项目改成了spring boot + mybatis,相对于来说优点太明显了
1. 创建独立的Spring应用程序
2. 嵌入的Tomcat,无需部署WAR文件
3. 简化Maven配置
4. 自动配置Spring
5. 提供生产就绪型功能,如指标,健康检查和外部配置
6. 绝对没有代码生成和对XML没有要求配置
这个是百度百科上面对spring boot 优点的描述,其实我感觉也是这样,大家可以试一下。
以下是具体的代码实现(github地址:https://github.com/yihec/spring-boot-mybatis)
首先是pom文件的一些依赖
4.0.0 com.example demo 20.0.1-SNAPSHOT jar demo 2 Demo project for Spring Boot org.springframework.boot spring-boot-starter-parent1.5.1.RELEASE UTF-8 UTF-8 1.7 org.springframework.boot spring-boot-starter-aoporg.springframework.boot spring-boot-starter-weborg.springframework.boot spring-boot-starter-loggingorg.springframework.boot spring-boot-starter-jdbccom.oracle ojdbc1410.2.0.1.0 org.springframework.boot spring-boot-starter-redisorg.springframework.boot spring-boot-starter-testtest org.mybatis mybatis-spring1.2.2 org.mybatis mybatis3.2.8 org.apache.commons commons-lang33.5 com.github.pagehelper pagehelper4.1.6 org.codehaus.jackson jackson-mapper-asl1.9.13 io.springfox springfox-swagger22.2.2 io.springfox springfox-swagger-ui2.2.2 org.springframework.boot spring-boot-starter-thymeleaforg.springframework.boot spring-boot-starter-log4jorg.springframework.boot spring-boot-maven-pluginspring-snapshots Spring Snapshots https://repo.spring.io/snapshot true spring-milestones Spring Milestones https://repo.spring.io/milestone false spring-snapshots Spring Snapshots https://repo.spring.io/snapshot true spring-milestones Spring Milestones https://repo.spring.io/milestone false
接着是application.yml数据库配置
spring: datasource: driver-class-name: oracle.jdbc.OracleDriver url: jdbc:oracle:thin:localhost:1521:orcl username: orcl password: orcl
然后是application.java
package com.example;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import javax.sql.DataSource;
@SpringBootApplication
//@ComponentScan 注解自动收集所有的Spring组件,包括 @Configuration 类。
@ComponentScan
@MapperScan("com.example.mapper")
public class DemoApplication {
@Bean
@ConfigurationProperties(prefix="spring.datasource")
public DataSource dataSource() {
return new org.apache.tomcat.jdbc.pool.DataSource();
}
@Bean
public SqlSessionFactory sqlSessionFactoryBean() throws Exception {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource());
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
//这里的话如果不用mybatis-config.xml 可以把下面那句给注释掉
sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:/mybatis
@Configuration
@EnableSwagger2
public class SwaggerConfig
{
@Bean
public Docket createRestApi() {
return new Docket(documentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.example.web"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("API")
.description("")
.termsOfServiceUrl("")
.contact("yihec")
.version("1.0")
.build();
}
}
最主要的代码就是这些了,然后大功告成,后面的都是个人的业务逻辑了。
