SSM完美整合
搭建整合环境
整合说明
整合方式有很多，我选择xml+注解的方式，单个maven工程（不使用maven父子工程）
整合思路
- 先搭建整合的环境
- 先把spring的配置搭建完成
- 在使用spring框架整合SpringMVC
- 最后使用Spring整合Mybatis
项目结构
首先引入依赖

编写实体类，及dao层
public class Account implements Serializable {
private Integer id;
private String name;
private Double money;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Double getMoney() {
return money;
}
public void setMoney(Double money) {
this.money = money;
}
@Override
public String toString() {
return "Account{" +
"id=" + id +
", name='" + name + '\'' +
", money=" + money +
'}';
}
}
@Repository("accountDao")
public interface AccountDao {
@Select("select *from account")
List<Account> findAll();
@Insert("insert into account(name,money) values(#{name},#{money})")
void saveAccount(Account account);
}
编写service层代码
@Service("accountService")
public class AccountServiceImpl implements AccountService {
@Autowired
@Qualifier("accountDao")
private AccountDao accountDao;
@Override
public List<Account> findAll() {
System.out.println("业务层，查询所有");
return accountDao.findAll();
}
@Override
public void saveAccount(Account account) {
System.out.println("业务层，保存账户");
accountDao.saveAccount(account);
}
}
编写controller层代码
@Controller
@RequestMapping("/account")
public class AccountController{
@Autowired
private AccountService accountService;
@RequestMapping("/findAll")
public String findAll(Model model){
System.out.println("表现层，查询所有账户。。。。。");
List<Account> accounts = accountService.findAll();
model.addAttribute("accounts",accounts);
//调用业务层的方法
return "list";
}
@RequestMapping("/save")
public void saveAccount(Account account, HttpServletRequest request,HttpServletResponse response) throws IOException {
System.out.println("表现层，保存账户。。。。。");
accountService.saveAccount(account);
//调用业务层的方法
response.sendRedirect(request.getContextPath()+"/account/findAll");
}
}
编写spring和mybatis的配置文件（合到一起）
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!--开启注解扫描,只处理service和dao-->
<context:component-scan base-package="com.hao">

<!--配置aop增强-->
<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.hao.service.impl.*ServiceImpl.*(..))"/>
</aop:config>
</beans>
编写SpringMVC的配置文件及Web.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"

<!-- 配置创建 spring 容器要扫描的包 ,只扫描controller注解-->
<context:component-scan base-package="com.hao">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--配置视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="viewResolver">
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>
<!--过滤静态资源-->
<mvc:resources mapping="/js/**" location="/js/"/>

<!--开启SpringMVC注解支持-->

编写index.js ， list.jsp ，success.jsp
