</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.9.8</version>
</dependency>
二、准备数据库表：
#创建数据库ssm
DROP DATABASE IF EXISTS ssm;
CREATE DATABASE ssm;
USE ssm;
#创建书本表
DROP TABLE IF EXISTS ssm_book;
CREATE TABLE ssm_book (
id INT(11) PRIMARY KEY AUTO_INCREMENT NOT NULL,
NAME VARCHAR(111),
detail VARCHAR(256),
userId INT(22)
);
INSERT INTO ssm_book(id, NAME,detail,userId) VALUES
(1,"javaWeb","JavaWeb从入门到精通",1),
(2,"PhotoShop","图片图像处理",1),
(3,"mysql从入门到精通","数据库专业书籍",2);
三、创建POJO：Book.java
public class Book implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String name;
private String detail;
private Integer userId;
}
四、创建jdbc.properties文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8
jdbc.username=root
jdbc.password=admin
五、创建applicationContext.xml配置文件
<!-- 配置读取properties文件jdbc.properties以连接数据库 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 配置数据源-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${admin}"/>
</bean>
<!-- 配置sqlSessionFactory -->
<bean class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="typeAliasesPackage" value="com.ssm.pojo"/>
</bean>
<!-- 配置mapper扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.ssm.mapper"/>
</bean>
<!-- 配置service扫描器 -->
<context:component-scan base-package="com.ssm.service"/>
<!-- 配置事务-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!--配置事务-通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED"/>
<tx:method name="delete*" propagation="REQUIRED"/>
<tx:method name="find*" propagation="REQUIRED"/>
<tx:method name="edit*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
<!-- 配置事务-切面 -->
<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.ssm.service.*.*(..))"/>
</aop:config>
六、创建springmvc-config.xml文件
<!-- 配置Controller扫描 -->
<context:component-scan base-package="com.ssm.controller"/>
<!-- 配置注解驱动 -->
<mvc:annotation-driven/>
<!-- 配置静态资源响应 -->
<mvc:default-servlet-handler/>
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
七、配置web.xml
<!-- needed for ContextLoaderListener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- Bootstraps the root web application context before servlet initialization -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
<servlet>
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Map all requests to the DispatcherServlet for handling -->
<servlet-mapping>
<servlet-name>springDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
八、创建映射Mapper:
BookMapper.java
public interface BookMapper {
public List<Book> findAll();
}
BookMapper.xml
<mapper namespace="com.ssm.mapper.BookMapper">
<select id="findAll" resultType="Book">
select * from ssm_book
</select>
</mapper>
九、创建服务层：
IBookService.java
public interface IBookService {
public List<Book> findAllBook();
}
BookServiceImpl.java
@Service
public class BookServiceImpl implements IBookService {
@Autowired
private BookMapper bookMapper;
@Override
public List<Book> findAllBook() {
return bookMapper.findAll();
}
}
十、创建控制器：BookController.java
@Controller
public class BookController {
@Autowired
private IBookService bookService;
@RequestMapping(value="/main")
public String Main(Model model) {
List<Book> books = bookService.findAllBook();
model.addAttribute("books",books);
return "main";
}
}
十一、创建视图：main.jsp
