SSM和Spring Boot經常使用配置比較
一.Dao層相關
1.Mysql相關：
1.1配置DataSource鏈接池:
（1）SSM配置：html
1 <!-- 加密後配置本身寫的解析文件 --> 2 <bean class="com.swpu.o2o.util.EncryptPropertyPlaceholderConfigurer"> 3 <property name="locations"> 4 <list> 5 <!-- 須要解密的文件 --> 6 <value>classpath:jdbc.properties</value> 7 <value>classpath:redis.properties</value> 8 </list> 9 </property> 10 <!-- 設置編碼爲UTF-8 --> 11 <property name="fileEncoding" value="UTF-8"></property> 12 </bean>
1 <bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource"> 2 <!-- 配置鏈接池屬性 --> 3 <property name="driverClass" value="${jdbc.driver}" /> 4 <property name="jdbcUrl" value="${jdbc.url}" /> 5 <property name="user" value="${jdbc.username}" /> 6 <property name="password" value="${jdbc.password}" /> 7 <!-- c3p0鏈接池的私有屬性 --> 8 <property name="maxPoolSize" value="30" /> 9 <property name="minPoolSize" value="10" /> 10 <!-- 關閉鏈接後不自動commit --> 11 <property name="autoCommitOnClose" value="false" /> 12 <!-- 獲取鏈接超時時間 --> 13 <property name="checkoutTimeout" value="10000" /> 14 <!-- 當獲取鏈接失敗重試次數 --> 15 <property name="acquireRetryAttempts" value="2" /> 16 </bean>
（2）Spring Boot配置（寫入Bean）java
1 package com.swpu.o2o.config.dao; 2 3 import com.mchange.v2.c3p0.ComboPooledDataSource; 4 import com.swpu.o2o.util.DESUtils; 5 import org.mybatis.spring.annotation.MapperScan; 6 import org.springframework.beans.factory.annotation.Value; 7 import org.springframework.context.annotation.Bean; 8 import org.springframework.context.annotation.Configuration; 9 10 import java.beans.PropertyVetoException; 11 12 /** 13 * 配置dataSource到ioc容器裏 14 */ 15 @Configuration 16 //配置mybatis mapper掃描路徑 17 @MapperScan("com.swpu.o2o.dao") 18 public class DataSourceConfiguration { 19 //經過@Value標籤獲取application.properties中的配置信息 20 @Value("${jdbc.driver}") 21 private String jdbcDriver; 22 @Value("${jdbc.url}") 23 private String jdbcUrl; 24 @Value("${jdbc.username}") 25 private String jdbcUser; 26 @Value("${jdbc.password}") 27 private String jdbcPassword; 28 /** 29 * 生成與與spring-dao.xml對應的bean dataSource 30 */ 31 @Bean(name="dataSource") 32 public ComboPooledDataSource createDataSource() throws PropertyVetoException { 33 //生成dataSource實例 34 ComboPooledDataSource dataSource=new ComboPooledDataSource(); 35 //配置相關信息（和配置文件同樣） 36 //驅動(強制異常處理，拋出去) 37 dataSource.setDriverClass(jdbcDriver); 38 //數據庫鏈接url 39 dataSource.setJdbcUrl(jdbcUrl); 40 //用戶名(解密) 41 dataSource.setUser(DESUtils.getDecryptString(jdbcUser)); 42 //密碼 43 dataSource.setPassword(DESUtils.getDecryptString(jdbcPassword)); 44 return dataSource; 45 } 46 }
1.2建立SqlSessionFactoryBean實例（設置設置mybatis configuration掃描路徑,mapper映射路徑，配置掃描Dao接口包等）
（1）SSM配置:web
1 <!-- 3.配置SqlSessionFactory對象 --> 2 <bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory"> 3 <!-- 注入數據庫鏈接池 --> 4 <property name="dataSource" ref="dataSource" /> 5 <!-- 配置MyBaties全局配置文件:mybatis-config.xml --> 6 <property name="configLocation" value="classpath:mybatis-config.xml" /> 7 <!-- 掃描entity包 使用別名 --> 8 <property name="typeAliasesPackage" value="com.swpu.o2o.entity" /> 9 <!-- 掃描sql配置文件:mapper須要的xml文件 --> 10 <property name="mapperLocations" value="classpath:mapper/*.xml" /> 11 </bean> 12 <!-- 4.配置掃描Dao接口包，動態實現Dao接口，注入到spring容器中 --> 13 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 14 <!-- 注入sqlSessionFactory --> 15 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> 16 17 <!-- 給出須要掃描Dao接口包 --> 18 <property name="basePackage" value="com.swpu.o2o.dao" /> 19 </bean>
（2）Spring Boot配置:redis
1 package com.swpu.o2o.config.dao; 2 3 import org.mybatis.spring.SqlSessionFactoryBean; 4 import org.springframework.beans.factory.annotation.Autowired; 5 import org.springframework.beans.factory.annotation.Value; 6 import org.springframework.context.annotation.Bean; 7 import org.springframework.context.annotation.Configuration; 8 import org.springframework.core.io.ClassPathResource; 9 import org.springframework.core.io.support.PathMatchingResourcePatternResolver; 10 import org.springframework.core.io.support.ResourcePatternResolver; 11 12 import javax.sql.DataSource; 13 import java.io.IOException; 14 15 @Configuration 16 public class SessionFactoryConfiguration { 17 //mybatis-config.xml配置文件路徑 18 //注意:靜態(static)的變量不能直接經過@Value獲取，能夠經過set方法 19 private static String mybatisConfigFile; 20 //mybatis mapper文件所在路徑 21 private static String mapperPath; 22 23 @Value("${mybatis_config_file}") 24 public void setMybatisConfigFile(String mybatisConfigFile) { 25 SessionFactoryConfiguration.mybatisConfigFile = mybatisConfigFile; 26 } 27 28 @Value("${mapper_path}") 29 public void setMapperPath(String mapperPath) { 30 SessionFactoryConfiguration.mapperPath = mapperPath; 31 } 32 33 //實體類所在package 34 @Value("${type_alias_package}") 35 private String typeAliasPackage; 36 @Autowired 37 private DataSource dataSource; 38 /** 39 * 建立SqlSessionFactoryBean實例，而且設置mapper映射路徑 40 * 設置dataSource數據源 41 */ 42 @Bean(name = "sqlSessionFactory") 43 public SqlSessionFactoryBean createSqlSessionFactoryBean() throws IOException { 44 SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean(); 45 //設置mybatis configuration掃描路徑 46 sqlSessionFactoryBean.setConfigLocation(new ClassPathResource(mybatisConfigFile)); 47 //設置mapper 掃描路徑 48 PathMatchingResourcePatternResolver pathMatchingResourcePatternResolver = new PathMatchingResourcePatternResolver(); 49 String packageSearchPath = ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX + mapperPath; 50 sqlSessionFactoryBean.setMapperLocations(pathMatchingResourcePatternResolver.getResources(packageSearchPath)); 51 //設置dataSource 52 sqlSessionFactoryBean.setDataSource(dataSource); 53 //設置typeAlias包掃描路徑 54 sqlSessionFactoryBean.setTypeAliasesPackage(typeAliasPackage); 55 return sqlSessionFactoryBean; 56 } 57 }
（3）Mybatis配置文件：spring
1 <?xml version="1.0" encoding="UTF-8"?> 2 <!DOCTYPE configuration 3 PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 5 <configuration> 6 <!-- 配置全局屬性 --> 7 <settings> 8 <!-- 使用jdbc的getGeneratedKeys獲取數據庫自增主鍵值 --> 9 <setting value="true" name="useGeneratedKeys" /> 10 <!-- 使用列別名替換列名 默認:true --> 11 <setting value="true" name="useColumnLabel" /> 12 <!-- 開啓駝峯命名轉換:Table{create_time} -> Entity{createTime} --> 13 <setting value="true" name="mapUnderscoreToCamelCase" /> 14 <!-- 打印查詢語句 --> 15 </settings> 16 17 </configuration>
2.Redis:
