                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

添加log4j配置文件

路径resources/log4j.properties
由于MyBatis依赖与log4j输出sql语句信息，所以需要配置log4j配置文件。

#设置输出级别和输出位置
log4j.rootLogger=debug,Console
#设置控制台相关的参数
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n  
#设置MyBatis的输出内容
log4j.logger.java.sql.ResultSet=INFO  
log4j.logger.org.apache=INFO  
log4j.logger.java.sql.Connection=DEBUG  
log4j.logger.java.sql.Statement=DEBUG  
log4j.logger.java.sql.PreparedStatement=DEBUG

配置web.xml

配置初始化spring文件路径,spring上下文加载监听器

<!-- 配置初始化spring文件路径 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/spring*.xml</param-value>
</context-param>

<!-- spring上下文加载监听器 -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

添加SpringMVC核心控制器DispatcherServlet配置信息


<!-- 配置SpringMVC的处理请求的Servlet -->
<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <!-- 表示系统启动时自动加载这个servlet -->
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

添加编码过滤器

添加乱码过滤器，避免提交时出现乱码

<!-- 开启编码过滤器 -->
<filter>
    <description>字符集过滤器</description>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <description>字符集编码</description>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

配置springmvc.xml

添加springmvc的配置文件，设置自动扫描包路径，静态资源处理，视图解析器等

配置sqlSessionFactory

resources/spring/spring-jdbc.xml
Mybatis中使用sqlSessionFactory来生产session对象，和Hibernate中相似，也可以交由spring来管理
设置扫描的映射文件和dao包

<!-- 配置mybatis session工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <!-- 指定mybatis的配置文件(可有可无) -->
    <property name="configLocation" value="classpath:mybatis-config.xml"></property>
    <property name="mapperLocations" value="classpath:mybatis-mapping/*.xml"></property>
</bean>

<!-- mybatyis扫描机制 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <!-- dao接口的扫描包 （如果有多个可以用,逗号隔开）-->
    <property name="basePackage" value="com.znsd.maven.ssm"></property>
    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    <property name="annotationClass" value="org.springframework.stereotype.Repository"></property>
</bean>

Mybatis映射文件

resources/mybatis-mapping
在SSM中，可以省略mybatis配置文件，也可以添加，只不过需要在sqlSessionFactory中配置configLocation属性即可。

<?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>
    <!-- 取别名，这个必须按照一定的顺序配置 -->
    <typeAliases>
        <!-- 将这个包下面的所有的类全部倒入进来，明明规则就是类名首字母小写 -->
        <package name="com.lxit.ssm.entities"/>
        <!-- 指定单独一个类的别名 -->
        <!-- <typeAlias type="com.lxit.ssm.entities.Student" alias="stu"/> -->
    </typeAliases>
  </configuration>

配置事务

resources/spring/spring-jdbc.xml
在Spring里面，可以通过AOP来管理事务，非常强大。

  <!-- 定义事务管理器（声明式的事务） -->
  <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
      <property name="dataSource" ref="dataSource" />
  </bean>

<!-- 启动注解方式事务管理器 -->
<!-- <tx:annotation-driven transaction-manager="txManager"/> -->

<!-- 事务的通知方式 -->
<tx:advice id="txAdvice" transaction-manager="txManager">
    <tx:attributes>
        <tx:method name="find*" propagation="REQUIRED" read-only="true" />
        <tx:method name="search*" propagation="REQUIRED" read-only="true" />
        <tx:method name="query*" propagation="REQUIRED" read-only="true" />

        <tx:method name="add*" propagation="REQUIRED" />
        <tx:method name="submit*" propagation="REQUIRED" />
        <tx:method name="save*" propagation="REQUIRED" />
        <tx:method name="insert*" propagation="REQUIRED" />

        <tx:method name="del*" propagation="REQUIRED" />
        <tx:method name="remove*" propagation="REQUIRED" />

        <tx:method name="update*" propagation="REQUIRED" />
        <tx:method name="modify*" propagation="REQUIRED" />

        <tx:method name="*" propagation="REQUIRED" read-only="true" />
    </tx:attributes>
</tx:advice>

实现查询学生列表信息

添加实体类

学生实体类

public class Student implements Serializable {
    
    private Integer id;
    private String name;
    private Integer age;
    @DateTimeFormat(pattern = "yyyy-MM-dd") // 日期格式化
    private Date birthday;
    
    // 省略getter和setter方法
}

映射文件

StudentDao接口

  @Repository
  public interface StudentDao {
    public List<Student> selectList();
  }

隐射文件StudentMapper.xml

  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
  <mapper namespace="com.znsd.ssm.dao.StudentDao">

    <resultMap id="BaseResultMap" type="com.znsd.ssm.bean.Student">
        <id column="id" property="id" jdbcType="INTEGER" />
        <result column="name" property="name" jdbcType="VARCHAR" />
        <result column="password" property="password" jdbcType="VARCHAR" />
        <result column="gender" property="gender" jdbcType="VARCHAR" />
        <result column="c_id" property="clazz.classId" jdbcType="INTEGER" />
    </resultMap>

    <select id="selectList" resultMap="BaseResultMap">
        select * from t_student
    </select>

  </mapper>

Service层

StudentService代码

  public interface StudentService {
    public List<Student> selectList();
  }

StudentService实现类

  @Service
  public class StudentServiceImpl implements StudentService {

    @Resource
    private StudentDao studentDao;

    @Override
    public List<Student> selectList() {
        return this.studentDao.selectList();
    }
  }

Controller层

由控制器层将数据返回对应的视图，输出json格式的数据

  @Controller
  @RequestMapping("student")
  public class StudentController {

    @Autowired
    private StudentService service;

    @RequestMapping("/list")
    public String getStudentList(Map<String, Object> map) {
        List<Student> studentList = service.selectList();
        map.put("studentList", studentList);
        return "studentList";
    }

    @ResponseBody
    @RequestMapping("/json")
    public List<Student> getlistJson() {
        List<Student> list = service.selectList();
        return list;
    }
  }

View视图层

显示学生列表

<!-- c标签 -->
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!-- 时间 -->
<%@taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

  <table width="500" border="1">
      <tr>
          <td>id</td>
          <td>name</td>
          <td>pass</td>
          <td>sex</td>
      </tr>
      <c:forEach items="${studentList}" var="stu">
          <tr>
            <td>${student.id}</td>
            <td>${student.name}</td>
            <td>${student.age}</td>
            <td>
                <fmt:formatDate value="${student.birthday}" pattern="YYYY-mm-dd"/>
            </td>
          </tr>
      </c:forEach>
  </table>
