maven主要依赖jar

<!--测试包-->    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>4.11</version>      <!-- 表示开发的时候引入，发布的时候不会加载此包 -->      <scope>test</scope>    </dependency>    <!-- 日志适配器 -->    <dependency>      <groupId>org.apache.logging.log4j</groupId>      <artifactId>log4j-slf4j-impl</artifactId>      <version>2.5</version>    </dependency>    <!-- 日志实现 -->    <dependency>      <groupId>org.apache.logging.log4j</groupId>      <artifactId>log4j-core</artifactId>      <version>2.5</version>    </dependency>    <!--1)spring核心依赖 -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>      <version>4.1.6.RELEASE</version>    </dependency>    <!--spring ioc依赖 -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-beans</artifactId>      <version>4.1.6.RELEASE</version>    </dependency>    <!--2 spring坐标依赖 -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>      <version>4.1.6.RELEASE</version>    </dependency>    <!--5spring test相关依赖 -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-test</artifactId>      <version>4.1.6.RELEASE</version>    </dependency>    <!--3 spring web相关依赖 -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>4.1.6.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-web</artifactId>      <version>4.1.6.RELEASE</version>    </dependency>    <!--4spring dao层依赖 -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-jdbc</artifactId>      <version>4.1.6.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-tx</artifactId>      <version>4.1.6.RELEASE</version>    </dependency>    <!-- 引入mybatis依赖坐标 -->    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis</artifactId>      <version>3.2.6</version>    </dependency>    <!-- 数据库连接池的包 -->    <dependency>      <groupId>org.apache.commons</groupId>      <artifactId>commons-dbcp2</artifactId>      <version>2.1.1</version>    </dependency>    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis-spring</artifactId>      <version>1.3.0</version>    </dependency>    <!--mysql驱动包-->    <dependency>      <groupId>mysql</groupId>      <artifactId>mysql-connector-java</artifactId>      <version>5.1.32</version>    </dependency>    <!-- 引入jstl包 -->    <dependency>      <groupId>jstl</groupId>      <artifactId>jstl</artifactId>      <version>1.2</version>    </dependency>    <dependency>      <groupId>com.fasterxml.jackson.core</groupId>      <artifactId>jackson-core</artifactId>      <version>2.5.4</version>    </dependency>    <dependency>      <groupId>com.fasterxml.jackson.core</groupId>      <artifactId>jackson-databind</artifactId>      <version>2.5.4</version>    </dependency>

spring-mybatis.xml

配置是一直数据库连接不上找到错误 db.properties 文件配置错误导致链接不上数据库

<!--引入配置文件-->    <bean id="propertyConfigurer"          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="location" value="classpath:db.properties" />    </bean>    <!--链接数据库   数据源-->    <bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource"        destroy-method="close">        <property name="driverClassName" value="${driver}"></property>        <property name="url" value="${url}"></property>        <property name="username" value="${username}"></property>        <property name="password" value="${password}"></property>    </bean>    <!--mapper读取-->    <bean id="splSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource"/>        <property name="mapperLocations" value="classpath:Mapper/*.xml"/>    </bean>    <!--dao接口所在位置-->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="come.one.dao"/>        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>    </bean>

@Controller 注解无法添加因为再加入jar包是添加如下问题

<dependency>            <groupId>javax.servlet.jsp</groupId>            <artifactId>jsp-api</artifactId>            <version>2.1</version>            <scope>runtime</scope>            <classifier />        </dependency>

因为maven 中cope对项目jar有限制具体参见点击打开链接
spring-mvc.xml
