基于一個(gè)完整的極簡(jiǎn)后臺(tái)框架http://www.reibang.com/p/871e70b3ad7c這篇文章受到了廣大程序愛好者的喜愛，說明在目前公司級(jí)別的項(xiàng)目中SpringBoot的重要性所以本人決定寫一個(gè)系列關(guān)于SpringBoot在項(xiàng)目中的實(shí)戰(zhàn)文章异赫，希望大家喜歡椅挣！
程序結(jié)構(gòu)如下：
數(shù)據(jù)庫表結(jié)構(gòu)如下

創(chuàng)建SpringBoot工程并在Pom.xml中添加依賴

項(xiàng)目的配制資源：
- DataSourceConfiguration 數(shù)據(jù)源的配制
package com.foreknow.config.dao;
import com.mchange.v2.c3p0.ComboPooledDataSource;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.beans.PropertyVetoException;
/**
* Created by imac on 2019/3/5.
*/
@Configuration
//mapper的掃描路徑
@MapperScan("com.foreknow.dao")
public class DataSourceConfiguration {
@Value("${jdbc.driver}")
private String jdbcDriver;
@Value("${jdbc.url}")
private String jdbcUrl;
@Value("${jdbc.username}")
private String jdbcUsername;
@Value("${jdbc.password}")
private String jdbcPassword;
@Bean(name = "dataSource")
public ComboPooledDataSource createDataSource() throws PropertyVetoException {
ComboPooledDataSource dataSource = new ComboPooledDataSource();
dataSource.setDriverClass(jdbcDriver);
dataSource.setJdbcUrl(jdbcUrl);
dataSource.setUser(jdbcUsername);
dataSource.setPassword(jdbcPassword);
dataSource.setAutoCommitOnClose(false);
return dataSource;
}
}
2.會(huì)話工廠的配制SessionFactoryConfiguration
package com.foreknow.config.dao;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import javax.sql.DataSource;
import java.io.IOException;
/**
* Created by imac on 2019/3/5.
*/
@Configuration
public class SessionFactoryConfiguration {
@Value("${mybatis_config_file}")
private String mybatisConfigFilePath;
@Value("${mapper_path}")
private String mapperPath;
@Value("${entity_package}")
private String entityPackage;
@Autowired
private DataSource dataSource;
@Bean(name="sqlSessionFactory")
public SqlSessionFactoryBean createSqlSessionFactoryBean() throws IOException {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setConfigLocation(new ClassPathResource(mybatisConfigFilePath));
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
String packageSearchPath = PathMatchingResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX+mapperPath;
//SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setMapperLocations(resolver.getResources(packageSearchPath));
sqlSessionFactoryBean.setDataSource(dataSource);
sqlSessionFactoryBean.setTypeAliasesPackage(entityPackage);
return sqlSessionFactoryBean;
}
}
3.業(yè)務(wù)層事物的配制TransactionManagementConfiguration
package com.foreknow.config.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.annotation.TransactionManagementConfigurer;
import javax.sql.DataSource;
/**
* Created by imac on 2019/3/5.
*/
@Configuration
@EnableTransactionManagement
public class TransactionManagementConfiguration implements TransactionManagementConfigurer {
@Autowired
private DataSource dataSource;
@Override
public PlatformTransactionManager annotationDrivenTransactionManager() {
return new DataSourceTransactionManager(dataSource);
}
}
