Preface ： If you're a little bit spring There is no basis for , I suggest you don't study springboot, At least one spring Project experience or self built spring Project relearning springboot, So you'll find that in spring What I don't understand in English , stay springboot Get some answers in .springboot The principle of “ Convention over configuration ”, So it's using springboot If there's a problem when you're on the road , There's no foundation , It's very difficult to solve the problem .

The goal is ： take spring Configuration in the container of ： Configuration of database , The timer configuration is converted to springboot in , Realization spring And springbooot Configuration and docking of .

Database configuration conversion ：

spring The configuration of the database connection in is as follows 

<!-- Database instance -->

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

<property name="driverClassName" value="${jdbc.mybatis.driver}" />

<property name="url" value="${jdbc.mybatis.url}" />

<property name="username" value="${jdbc.mybatis.username}" />

<property name="password" value="${jdbc.mybatis.password}" />

<!-- Initialize connection size -->

<property name="initialSize" value="10" />

<!-- Maximum number of connection pools -->

<property name="maxActive" value="1000" />

<!-- Connection pool maximum idle -->

<property name="maxIdle" value="30" />

<!-- Connection pool minimum idle -->

<property name="minIdle" value="10" />

<!-- Get connection maximum wait time -->

<property name="maxWait" value="2000" />

</bean>

pringboot Configuration in 

 @Bean(name = "dataSource")

public BasicDataSource myGetDataSource() {

BasicDataSource dataSource = new BasicDataSource();

dataSource.setDriverClassName(driverClassName);

dataSource.setUrl(url);

dataSource.setPassword(passWord);

dataSource.setUsername(userName);

dataSource.setMaxIdle(2);

dataSource.setMaxActive(20);

dataSource.setMaxWait(1000);

dataSource.setInitialSize(2);
//

dataSource.setValidationQuery("SELECT 1");

dataSource.setRemoveAbandoned(true);

dataSource.setTestWhileIdle(true);

dataSource.setTimeBetweenEvictionRunsMillis(30000);

dataSource.setNumTestsPerEvictionRun(30);

dataSource.setMinEvictableIdleTimeMillis(1800000);

return dataSource;

}

spring Configuration in 

 <!-- spring and MyBatis Perfect integration , Unwanted mybatis Configuration map file -->

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="dataSource" />

<property name="mapperLocations" value="classpath:springMVCmybatis/com/my/mapper/*.xml" />

<!-- <property name="typeAliasesPackage" value="com.my.model"/> -->
</bean>

springboot To configure sqlSessionFactoryBean, Corresponding to the above sping Of SqlSessionFactoryBean class

.

@Bean(name = "sqlSessionFactoryBean")

public SqlSessionFactoryBean myGetSqlSessionFactory(DataSource dataSource) throws Exception {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
// mapperLocations

ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
try {

sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:mapper/*Mapper.xml"));

} catch (IOException e) {

log.info("sqlSessionFactoryBean Of setMapperLocations There is a problem ");

e.printStackTrace();

}
// dataSource
sqlSessionFactoryBean.setDataSource(dataSource);
// SqlSessionFactory sessionFactory = sqlSessionFactoryBean.getObject();
return sqlSessionFactoryBean;
}

spring Configuration in 

 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

<property name="basePackage" value="springMVCmybatis" />

<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>

springboot Configuration in 

package com.my.myconfigure;
import org.mybatis.spring.mapper.MapperScannerConfigurer;

import org.springframework.boot.autoconfigure.AutoConfigureAfter;

import org.springframework.context.annotation.Configuration;
//<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

//<property name="basePackage" value="springMVCmybatis" />

//<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />

//

//</bean>
@Configuration
// This annotation needs to be loaded MybatisDbConfigure.class And then load MapperScanConfig This class 

@AutoConfigureAfter(MybatisDbConfigure.class)

public class MapperScanConfig {
public MapperScannerConfigurer myGetMapperScannerConfigurer() {

MapperScannerConfigurer myMapperScannerConfigurer = new MapperScannerConfigurer();
myMapperScannerConfigurer.setBasePackage("com.my.dao");

myMapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactoryBean");

return myMapperScannerConfigurer;

}
}

Conclusion ：springboot It's through @Configuration To mark the custom configuration , Use... In configuration @Bean To add class functions and spring The configuration of the .xml Files work the same way , Both are the function of the container .

About this part of the configuration has been uploaded to my github On , Interested in or not understanding , You can log in to view .
