在前面的博文中，依次介绍了Spring、Spring mvc、Mybaits框架的功能及使用。在之前的博文中都是单独的介绍，尤其是Mybaits框架，在例子中跟本就没有用到其它的框架，这说明了他们的独立性，但反观之前的Mybaits的例子，测试的时候总是要先创建sqlSession，再获取mapper接口的动态代理对象，然后才能调用mapper对象的方法，而这些代码都是必须且重复的，十分的不便。这时，Spring的作用就发挥出来了。我们可以实现将所有对象创建和依赖关系维护交给Spring管理，Spring本身就是一个大工厂，负责bean的生产。
一般来说，先整合Spring和SpringMVC，再整合Spring和Mybaits，不过为了方便，我就直接发代码了，不分步骤，xml文件中会有详细的注释说明。以《JavaWeb高级编程》一书中的Discussion-Board工程为例，这个工程本身只是整合了Spring与Spring MVC，我在此工程的基础上添加了MySQL数据库并以Mybaits为框架，有略作修改。
首先是工程的整体结构目录：
这个工程的结构与普通直接创建的MAVEN工程有些不同，这是因为我在pom.xml文件中做了设置，只是个人喜好，不同也没有关系。
接下来是Maven的pom.xml文件
我就不显示我是怎么设置的了，其中有很多不需要的包，各种包有注释说明，依据个人需求吧，并不需要全部都写

</beans>这样Spring 、SpringMVC和Mybaits就整合完毕了，但是还确实Mybait的主配置文件，sqlMapConfig.xml(名字也随便你起，但要跟Spring配置文件中写的一致)，事实上什么都没有，因为没用上它的功能，比如开启缓存啊、setting设置啊之类的，主要是省了我们写mapper映射文件加载，Spring已经自动帮我们完成了。
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration

<configuration>
<!-- <properties resource=""></properties> -->
<typeAliases>
<package name="com.wrox.discussionboard.pojo"/>
</typeAliases>
</configuration>配置文件就是这样的了，上面的所有东西就已经将Spring、SpringMVC、Mybaits整合完成了，接下是Discussion-Board功能的具体实现。
首先是POJO类，结构如下：
只列出属性，注意一定要有get、set方法
public class Reply implements Serializable{
private static final long serialVersionUID = 1L;
private Integer id;
private Integer discussionId;
private String user;
private String message;
private LocalDateTime created;public class Discussion implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String user;
private String subject;
private String uriSafeSubject;
private String message;
private LocalDateTime created;
private LocalDateTime lastUpdated;
private Set<String> subscribedUsers = new HashSet<>();public class DiscussionForm implements Serializable{
private static final long serialVersionUID = 1L;
private String user;
private String subject;
private String message;public class ReplyForm implements Serializable{
private static final long serialVersionUID = 1L;
private String user;
private String message;接下来时mapper接口类，也就是在平常的Dao层：
public interface DiscussionMapper {
List<Discussion> getAll();
Discussion get(int id);
void add(Discussion discussion);
void update(Discussion discussion);
}public interface ReplyMapper {
List<Reply> getForDiscussion(int id);
void add(Reply reply);
void update(Reply reply);
}mapper映射文件代码如下：
ReplyMapper.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.wrox.discussionboard.mapper.ReplyMapper">
<select id="getForDiscussion" parameterType="int" resultType="com.wrox.discussionboard.pojo.Reply">
select * from reply where discussionId = #{discussionId}
</select>
<insert id="add" parameterType="com.wrox.discussionboard.pojo.Reply">
insert into reply(discussionId,user,message,created)
values (#{discussionId},#{user},#{message},#{created})
</insert>
<update id="update" parameterType="com.wrox.discussionboard.pojo.Reply">
update reply set message = #{message}, created = #{created} where id = #{id}
</update>
</mapper>DiscussionMapper.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.wrox.discussionboard.mapper.DiscussionMapper">
<select id="getAll" resultType="com.wrox.discussionboard.pojo.Discussion">
select * from discussion
</select>
<select id="get" resultType="com.wrox.discussionboard.pojo.Discussion" parameterType="int">
select * from discussion where id = #{id}
</select>
<insert id="add" parameterType="com.wrox.discussionboard.pojo.Discussion">
insert into discussion(user,subject,uriSafeSubject,message,created,lastUpdated)
values(#{user},#{subject},#{uriSafeSubject},#{message},#{created},#{lastUpdated})
</insert>
<update id="update" parameterType="com.wrox.discussionboard.pojo.Discussion">
update discussion set subject = #{subject} ,uriSafeSubject = #{uriSafeSubject} , lastUpdated= #{lastUpdated} where id = #{id}
</update>
</mapper>然后是Service层，采用面向接口编程的方式，结构如下：
接口文件如下：
public interface DiscussionService {
List<Discussion> getAllDiscussion();
Discussion getDiscussion(int id);
void saveDiscussion(Discussion discussion);
}public interface ReplyService {
List<Reply> getRepliesForDiscussion(int discussionId);
void saveReply(Reply reply);
}接口实现类如下:
@Service
public class DefaultDiscussionService implements DiscussionService{
@Autowired
DiscussionMapper discussionMapper;
@Override
public List<Discussion> getAllDiscussion() {
List<Discussion> list = this.discussionMapper.getAll();
list.sort((d1,d2) -> d1.getLastUpdated().compareTo(d2.getLastUpdated()));
return list;
}
@Override
public Discussion getDiscussion(int id) {
// TODO Auto-generated method stub
return this.discussionMapper.get(id);
}
@Override
public void saveDiscussion(Discussion discussion) {
// TODO Auto-generated method stub
String subject = discussion.getSubject();
subject = Normalizer.normalize(subject.toLowerCase(), Normalizer.Form.NFD)
.replaceAll("\\p{InCombiningDiacriticalMarks}+", "")
.replaceAll("[^\\p{Alnum}]+", "-")
.replace("--", "-").replace("--", "-")
.replaceAll("[^a-z0-9]+$", "")
.replaceAll("^[^a-z0-9]+", "");
discussion.setUriSafeSubject(subject);
LocalDateTime now = LocalDateTime.now();
discussion.setLastUpdated(now);
if(discussion.getId() == null){
discussion.setCreated(now);
discussion.getSubscribedUsers().add(discussion.getUser());
this.discussionMapper.add(discussion);
}else
this.discussionMapper.update(discussion);
}
}@Service
public class DefaultReplyService implements ReplyService{
@Autowired
ReplyMapper replyMapper;
@Autowired
DiscussionService discussionService;
@Override
public List<Reply> getRepliesForDiscussion(int discussionId) {
List<Reply> list = this.replyMapper.getForDiscussion(discussionId);
list.sort((r1,r2) -> r1.getId()<r2.getId() ? -1:1);
return list;
}
@Override
public void saveReply(Reply reply) {
// TODO Auto-generated method stub
Discussion discussion = this.discussionService.getDiscussion(reply.getDiscussionId());
if(reply.getId() == null){
discussion.getSubscribedUsers().add(reply.getUser());
reply.setCreated(LocalDateTime.now());
this.replyMapper.add(reply);
}
else{
this.replyMapper.update(reply);
}
this.discussionService.saveDiscussion(discussion);
}
}最后是逻辑控制层，其实现如下：
@Controller
@RequestMapping("discussion")
public class BoradController {
@Autowired
DiscussionService discussionService;
@RequestMapping(value={"","list"},method = {RequestMethod.GET,RequestMethod.POST})
public String listDiscussions(Map<String,Object> model,HttpServletRequest request){
model.put("discussions",this.discussionService.getAllDiscussion());
return "discussion/list";
}
@RequestMapping(value="create",method = RequestMethod.GET)
public String createDiscussion(Map<String,Object> model,HttpServletRequest request){
model.put("discussionForm", new DiscussionForm());
return "discussion/create";
}
@RequestMapping(value="create",method = RequestMethod.POST)
public String createDiscussion(DiscussionForm from){
Discussion discussion = new Discussion();
discussion.setUser(from.getUser());
discussion.setSubject(from.getSubject());;
discussion.setMessage(from.getMessage());
this.discussionService.saveDiscussion(discussion);
return "forward:/discussion/list";
}
}@Controller
@RequestMapping("discussion/{discussionId:\\d+}")
public class DiscussionController {
@Autowired
DiscussionService discussionService;
@Autowired
ReplyService replyService;
@RequestMapping(value ={"","*"},method = RequestMethod.GET)
public String viewDiscussion(Map<String,Object> model,@PathVariable("discussionId") int id){
Discussion discussion = this.discussionService.getDiscussion(id);
if(discussion != null){
model.put("discussion", discussion);
model.put("replies", this.replyService.getRepliesForDiscussion(id));
model.put("replyForm", new ReplyForm());
return "discussion/view";
}
return "discussion/errorNoDiscussion";
}
@RequestMapping(value="reply",method=RequestMethod.POST)
public ModelAndView reply(ReplyForm form,@PathVariable("discussionId") int id){
Discussion discussion = this.discussionService.getDiscussion(id);
if(discussion != null){
Reply reply = new Reply();
reply.setDiscussionId(id);
reply.setUser(form.getUser());
reply.setMessage(form.getMessage());
this.replyService.saveReply(reply);
return new ModelAndView(new RedirectView("/discussion/"+id+"/"+discussion.getUriSafeSubject(),true,false));
}
return new ModelAndView("discussion/errorNoDiscussion");
}
}最后是视图层，其结构如果：
create.jsp文件代码如下：

pageEncoding="UTF-8"%>

</html>启动Tomcat,在浏览器地址中输入：http://localhost/Discussion-Board/discussion/list因有如下显示：
我是因为数据库中已经存有了信息才会有这些显示，如果数据库为空，应显示There are no discussions yet.
这篇博文提醒了我要搞个github账户来玩一玩，否则的话非重点的代码实在是太多了！！
