開發環境：

System：Windows server 2003

WebBrowser：IE6+、Firefox3+

JavaEE Server：tomcat5.

IDE：eclipse、MyEclipse 6.5

Database：MySQL

開發依賴庫：

JavaEE5、Spring 3.0.5、Mybatis 3.0.2、myBatis-spring-1.0.0-rc2

1、首先新建一個WebProject 命名為ssi，新建項目時，使用JavaEE5的lib庫。然后手動添加需要的jar包，所需jar包如下：

2、添加spring的監聽及springMVC的核心Servlet，web.xml內容，內容如下：

org.springframework.web.context.ContextLoaderListenercontextConfigLocationclasspath:applicationContext-*.xmlspmvcorg.springframework.web.servlet.DispatcherServletspmvc*.doCharacterEncodingFilterorg.springframework.web.filter.CharacterEncodingFilterencodingutf-8CharacterEncodingFilter/*index.jsp

3、在WEB-INF目錄中添加spmvc-servlet.xml，內容如下：

http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

4、在src目錄下添加applicationContext-common.xml，內容如下：

classpath:com/hoo/mapper/*.xml

上面的配置最先配置的是DataSource，這里采用的是jdbc的DataSource；

然后是SqlSessionFactoryBean，這個配置比較關鍵。SqlSessionFactoryBean需要注入DataSource數據源，其次還要設置configLocation也就是mybatis的xml配置文件路徑，完成一些關于mybatis的配置，如settings、mappers、plugin等；

如果使用MapperScannerPostProcessor模式，會自動將basePackage中配置的包路徑下的所有帶有@Mapper標注的Mapper(dao)層的接口生成代理，替代原來我們的Mapper實現。

5、AccountMapper接口內容如下：

@Mapper("mapper")publicinterfaceAccountMapperextendsSqlMapper {publicListgetAllAccount();publicAccount getAccount();publicAccount getAccountById(String id);publicAccount getAccountByNames(String spring);

@Select("select * from account where username = #{name}")publicAccount getAccountByName(String name);publicvoidaddAccount(Account account);publicvoideditAccount(Account account);publicvoidremoveAccount(intid);

}

6、實體類和account-resultmap.xml

privatestaticfinallongserialVersionUID = -7970848646314840509L;privateInteger accountId;privateInteger status;privateString username;privateString password;privateString salt;privateString email;privateInteger roleId;//getter、setter@OverridepublicString toString()

{returnthis.accountId + "#" +this.status + "#" +this.username +? "#" +this.password +? "#" +this.email +? "#" +this.salt + "#" +this.roleId;

}

account-resultmap.xml

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">username, passwordinsert into account(account_id, status, username, password)

values(#{accountId}, #{status}, #{username}, #{password})select cast(random() * 10000 as Integer) a from #Tabinsert into account(account_id, status, username, password)

values(#{accountId}, #{status}, #{username}, #{password})update account set

status = #{status},

username = #{username},

password = #{password}

where account_id = #{accountId}delete from account where account_id = #{id}

7、在src目錄中添加applicationContext-beans.xml內容如下：

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

這里配置bean對象，一些不能用annotation注解的對象就可以配置在這里

8、在src目錄中添加mybatis.xml，內容如下：

在這個文件放置一些全局性的配置，如handler、objectFactory、plugin、以及mappers的映射路徑（由于在applicationContext-common中的SqlSessionFactoryBean有配置mapper的location，這里就不需要配置）等

9、定義AccountDao接口及實現代碼，代碼如下：

publicinterfaceAccountDao{publicbooleanaddAccount(T entity)throwsDataAccessException;publicT getAccount(Integer id)throwsDataAccessException;publicList getList()throwsDataAccessException;

}

接口實現

importjava.util.List;importjavax.inject.Inject;importorg.springframework.dao.DataAccessException;importorg.springframework.stereotype.Repository;importorg.springframework.beans.factory.annotation.Autowired;importcom.hoo.dao.AccountDao;importcom.hoo.entity.*;importcom.hoo.mapper.*;importorg.springframework.beans.factory.annotation.Qualifier;

@SuppressWarnings("unchecked")

@Repository("accountDaoImpl")publicclassAccountDaoImplimplementsAccountDao{

@Autowired(required=false)

@Qualifier("mapper")privateAccountMapper mapper;publicbooleanaddAccount(T entity)throwsDataAccessException {booleanflag=false;try{

mapper.addAccount(entity);

flag=true;

}catch(DataAccessException e)

{

flag=false;throwe;

}returnflag;

}publicT getAccount(Integer id)throwsDataAccessException {

T entity=null;try{

entity=(T)mapper.getAccountById(String.valueOf(id));

}catch(DataAccessException e)

{throwe;? ? ? }returnentity;

}publicList getList()throwsDataAccessException {return(List)mapper.getAllAccount();

}

10、服務層AccountBiz接口及實現代碼

接口：

publicinterfaceAccountBiz{publicbooleanaddAccount(T entity)throwsDataAccessException;publicT getAccount(Integer id)throwsDataAccessException;publicList getList()throwsDataAccessException;

}

實現代碼：

packagecom.hoo.biz.impl;importjava.util.List;importorg.springframework.dao.DataAccessException;importcom.hoo.biz.AccountBiz;importcom.hoo.entity.*;importjavax.inject.Inject;importcom.hoo.dao.*;importorg.springframework.stereotype.Service;importcom.hoo.exception.BizException;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.beans.factory.annotation.Qualifier;

@Service("accountBizImpl")publicclassAccountBizImplimplementsAccountBiz{

@Autowired

@Qualifier("accountDaoImpl")privateAccountDaodao;publicbooleanaddAccount(T entity)throwsDataAccessException {if(entity==null){thrownewBizException(Account.class.getName()+"對象參數為empty!");

}returndao.addAccount(entity);

}publicT getAccount(Integer id)throwsDataAccessException {returndao.getAccount(id);

}publicList getList()throwsDataAccessException {returndao.getList();

}

11、 springMVC的控制器，AccountController代碼如下：

packagecom.hoo.controller;importjavax.inject.Inject;importjavax.servlet.http.HttpServletRequest;importorg.springframework.stereotype.Controller;importorg.springframework.ui.Model;importorg.springframework.web.bind.annotation.ExceptionHandler;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RequestParam;importorg.springframework.beans.factory.annotation.Autowired;importcom.hoo.biz.AccountBiz;importcom.hoo.entity.Account;importorg.springframework.beans.factory.annotation.Qualifier;

@Controller("accountController")

@RequestMapping("/account")publicclassAccountController {

@Autowired

@Qualifier("accountBizImpl")privateAccountBizbiz;

@RequestMapping("/add")publicString add(@RequestParam String username, @RequestParam String password, @RequestParam String status)

{

Integer stat=Integer.valueOf(status);

Account acc=newAccount(username,password,stat);

System.out.println(acc);

biz.addAccount(acc);return"redirect:/account/list.do";

}

@RequestMapping("/get")publicString get(Integer id,Model model)

{

System.out.println("###ID:"+id);

model.addAttribute(biz.getAccount(id));return"/show.jsp";

}

@RequestMapping("/list")publicString list(Model model)

{

model.addAttribute("list",biz.getList());return"/list.jsp";

}

@ExceptionHandler(Exception.class)publicString exception(Exception e,HttpServletRequest request)

{

request.setAttribute("exception", e);return"/error.jsp";

}

12、基本頁面代碼
