maven中spring+springmvc+mybatis整合詳細配置
阿新 • • 發佈：2018-12-03
首先配置mybatis，可以參考這篇部落格的前期基礎配置使用。
https://blog.csdn.net/qq_41520636/article/details/84146699
下面配置結構：
需要的jar，在pom.xml中引入
<!--統一jar包--> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spring.vision>5.1.1.RELEASE</spring.vision> <shiro.version>1.2.3</shiro.version> </properties> <dependencies> <!--mybatis框架--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.6</version> </dependency> <!-- JUnit單元測試工具 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <!-- 表示開發的時候引入，釋出的時候不會載入此包 --> <scope>test</scope> </dependency> <!--mysql連線池jar包--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.38</version> </dependency> <!--快取--> <dependency> <groupId>org.mybatis.caches</groupId> <artifactId>mybatis-ehcache</artifactId> <version>1.1.0</version> </dependency> <!--列印日誌--> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.5</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.12</version> </dependency> <!--自動生成bean--> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> <!--toString與過載方法過濾--> <dependency> <groupId>cglib</groupId> <artifactId>cglib</artifactId> <version>3.1</version> </dependency> <dependency> <groupId>asm</groupId> <artifactId>asm</artifactId> <version>3.3.1</version> </dependency> <!--分頁--> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>5.1.8</version> </dependency> <!--spring框架核心庫--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.vision}</version> </dependency> <!-- spring-aop --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.vision}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.vision}</version> </dependency> <!--Spring java資料庫訪問包，在本例中主要用於提供資料來源 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.vision}</version> </dependency> <!--Spring Web--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.vision}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.vision}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.vision}</version> </dependency> <!--spring和mybatis整合--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.2</version> </dependency> <!-- aspectjweaver 切面--> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.9.2</version> </dependency> <!--最新版c3p0連線池--> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency>
下面是applicationContext.xml配置，連線資料庫事務的配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!--引入屬性檔案，在配置中佔位使用 --> <context:property-placeholder location="classpath:jdbc.properties"/> <!--配置C3P0資料來源--> <bean id="ds" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <!--連線資料庫的基本資訊--> <property name="user" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="jdbcUrl" value="${jdbc.url}" /> <property name="driverClass" value="${jdbc.driver}" /> <!--連線池的相應配置--> <property name="maxPoolSize" value="${maxPoolSize}"></property> <property name="minPoolSize" value="${minPoolSize}"></property> <property name="initialPoolSize" value="${initialSize}"></property> <property name="acquireIncrement" value="${acquireIncrement}"></property> <property name="autoCommitOnClose" value="${autoCommitOnClose}"></property> </bean> <!--配置mybatis的工廠--> <bean id="sessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"> <!--資料來源--> <property name="dataSource" ref="ds"></property> <!-- 配置MyBaties全域性配置檔案:mybatis-config.xml --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> <!--類的別名的包--> <property name="typeAliasesPackage" value="org.lisonglin.entity"></property> <!-- 掃描sql配置檔案:mapper需要的xml檔案 --> <property name="mapperLocations" value="classpath:org/lisonglin/mapper/*.xml" /> </bean> <!--spring和mybatis整合 (自動掃描對映介面)--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!--指定ioc容器中的mybatis工廠的bean的名字--> <property name="sqlSessionFactoryBeanName" value="sessionFactoryBean"></property> <!--mapper所在的包--> <property name="basePackage" value="org.lisonglin.mapper"></property> </bean> <!--宣告式事務管理--> <!--定義事物管理器，由spring管理事務 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="ds"></property> </bean> <!--支援註解驅動的事務管理，指定事務管理器 --> <!--事務屬性--> <tx:advice id="advice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="*" isolation="READ_COMMITTED" propagation="REQUIRED"/> <tx:method name="insert*" isolation="SERIALIZABLE" propagation="REQUIRED"></tx:method> </tx:attributes> </tx:advice> <!--配置事務(攔截service)--> <aop:config> <!--切入點表示式--> <aop:pointcut id="pc" expression="execution(* org.lisonglin.service.*.*(..))"></aop:pointcut> <!--關聯切入點表示式和事務屬性--> <aop:advisor advice-ref="advice" pointcut-ref="pc"></aop:advisor> </aop:config> <!--使事務註解起作用--> <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven> <!--只掃描controller的包以外的包--> <context:component-scan base-package="org.lisonglin"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:exclude-filter> </context:component-scan> <!--aspectj支援自動代理實現AOP功能--> <aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy> <!-- 攔截器方式配置事物 --> <tx:advice id="transactionAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="append*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="modify*" propagation="REQUIRED" /> <tx:method name="edit*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="repair" propagation="REQUIRED" /> <tx:method name="delAndRepair" propagation="REQUIRED" /> <tx:method name="get*" propagation="SUPPORTS" /> <tx:method name="find*" propagation="SUPPORTS" /> <tx:method name="load*" propagation="SUPPORTS" /> <tx:method name="search*" propagation="SUPPORTS" /> <tx:method name="datagrid*" propagation="SUPPORTS" /> <tx:method name="*" propagation="SUPPORTS" /> </tx:attributes> </tx:advice> </beans>
對應的jdbc.properties配置，如果出現以下錯誤
spring連線c3p0出現錯誤 Connections could not be acquired from the underlying database!
可以檢視這篇部落格解決方案
https://blog.csdn.net/qq_41520636/article/details/84344133
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/stus?useUnicode=true&characterEncoding=utf8&useSSL=false jdbc.username=root jdbc.password=123 #最大連線數 maxPoolSize=100 #最小連線數 minPoolSize=20 # 關閉連線後不自動commit autoCommitOnClose=false # 獲取連線超時時間 checkoutTimeout=10000 # 初始化連線 initialSize=30 #driver default 指定由連線池所建立的連線的只讀（read-only）狀態。 #如果沒有設定該值，則“setReadOnly”方法將不被呼叫。（某些驅動並不支援只讀模式，如：Informix） defaultReadOnly= #driver default 指定由連線池所建立的連線的事務級別（TransactionIsolation）。 #可用值為下列之一：（詳情可見javadoc。）NONE,READ_UNCOMMITTED, READ_COMMITTED, REPEATABLE_READ, SERIALIZABLE defaultTransactionIsolation=READ_UNCOMMITTED #連線數 acquireIncrement=30
在然後是mybatis-config.xml配置
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 配置全域性屬性 -->
<settings>
<!--允許返回多個結果集-->
<setting name="multipleResultSetsEnabled" value="true"></setting>

</settings>
<!-- mybatis分頁外掛 -->
<plugins>
<plugin interceptor="com.github.pagehelper.PageInterceptor"></plugin>
</plugins>
</configuration>接著是log4j.properties的配置
#---- global logging configuration
#---- level: FATAL,ERROR,WARN,INFO,DEBUG
#---- appender: console, file, mail
### set log levels ###
log4j.rootLogger = DEBUG,console
### 輸出到控制檯 ###
log4j.appender.console = org.apache.log4j.ConsoleAppender
log4j.appender.console.Target = System.out
log4j.appender.console.layout = org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern = %d{yyyy-MM-dd HH\:mm\:ss} %5p %c{1}:%L - %m%n
### 輸出到日誌檔案 ###
log4j.appender.file = org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File = ${webapp.root}/WEB-INF/logs/platform.log
log4j.appender.file.DatePattern=_yyyyMMdd'.log'
#log4j.appender.file.Append = true
#log4j.appender.file.Threshold = INFO
log4j.appender.file.layout = org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern =%-d{yyyy-MM-dd HH\:mm\:ss} [ %t\:%r ] - [ %p ] %m%n
### 列印SQL ###

log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
#log4j.logger.java.sql.ResultSet=DEBUG最後是spring-mvc.xml配置
