ssm框架搭建详细（spring4+struts2+mybatis3）
以前工作中，项目用的是ssm（spring，struts，mbatis）框架，但是自己没有搭建过，最近花了一段时间来整理学习了一下，把最近的收获分给大家，主要是ssm的搭建。
1.首先我们要准备好自己框架所需要的jar包
1.1 struts2所需jar包：包括整合spring的jar包
1.2 spring所需的jar包：我这里是把spring的所有核心jar包都考了进来
1.3 mybatis所需要的jar包和其他，链接数据库，log4j，的jar包
上面是所需要的jar包，由于是后来才写的博文，有可能还有不全，忘大家多提意见！
2.配置xml配置文件
2.1 mybatis的配置文件内容：mybatis-config.xml
增删改查的操作，userinfoMapping.xml
id,username,password,sex,birthday,insertDate,message
insert into
userinfo(id,username,password,sex,birthday,message,insertDate)
values(#{id},#{username},#{password},#{sex},#{birthday,jdbcType=DATE},#{message,jdbcType=CLOB},sysdate)
delete from userinfo where id = #{id}
update userinfo set
name=#{name},sex=#{sex},birthday=#{birthday},message=#{message}
where
id=#{id}
update userinfo set
username=#{username},
sex=#{sex},
birthday=#{birthday},
message=#{message},
where id=#{id}
2.2 struts配置文件的内容：struts.xml
2.3 spring的配置文件的内容，有详细的注解：applicationContext.xml
!-- -->
pringle.xml的内容
2.4数据库连接的文件：jdbc.properties，这里要根据我们需要的数据库进行不同的修改，我是使用 的Oracle
db.driver=oracle.jdbc.driver.OracleDriver
db.url=jdbc:oracle:thin:@localhost:1521:orcl
db.username=user1
db.password=user1
2.5 log4j的文件：自己根据情况自己配置
llog4j.rootLogger = debug, stdout, R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %p %d{yyyy-MM-dd HH:mm:ss} -- %m -- %l%n
###file logger###
log4j.appender.R = org.apache.log4j.RollingFileAppender
log4j.appender.R.File = d:/logs/lylg.log
log4j.appender.R.MaxFileSize = 1Mb
log4j.appender.R.MaxBackupIndex = 100
log4j.appender.R.layout = org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern =%p %d{yyyy-MM-dd HH\:mm\:ss} -- %m -- %l%n
log4j.logger.org.springframework=debug,console
log4j.logger.org.apache.ibatis = ERROR
log4j.logger.com.ibatis=ERROR
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=ERROR
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=ERROR
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=ERROR
log4j.logger.java.sql.Connection = ERROR
log4j.logger.java.sql.Statement = ERROR
log4j.logger.java.sql.PreparedStatement = ERROR
log4j.logger.java.sql.ResultSet = ERROR
3. 在数据库中创建我们相应的表：Userinfo
create table USERINFO
(
ID VARCHAR2(32) not null,
USERNAME VARCHAR2(20),
PASSWORD VARCHAR2(20),
SEX VARCHAR2(2),
INSERTDATE DATE,
MESSAGE CLOB,
PIC BLOB,
BIRTHDAY DATE
)
-- Add comments to the columns
comment on column USERINFO.ID
is 'id';
comment on column USERINFO.USERNAME
is '用户名';
comment on column USERINFO.PASSWORD
is '密码';
comment on column USERINFO.SEX
is '性别';
comment on column USERINFO.INSERTDATE
is '入库时间';
comment on column USERINFO.MESSAGE
is '长数据';
comment on column USERINFO.PIC
is '头像';
comment on column USERINFO.BIRTHDAY
is '生日';4.编写我们的类
4.1先创建我们的dao接口，这里是利用alldao的思路实现的，所以又一个all到类
public interface IUserinfoDao {
public int insertUserinfo(Userinfo userinfo);
public List selectPage(PageModel page);
public long userCount(Map pageMap);
public void deleteById(String id);
public Userinfo queryById(String id);
public int updateById(Userinfo userinfo);
public int updateBySelective(Userinfo userinfo);
}
@Repository
public class AllDao {
@Autowired
private IUserinfoDao userinfodao;
public IUserinfoDao getUserinfodao() {
return userinfodao;
}
public void setUserinfodao(IUserinfoDao userinfodao) {
this.userinfodao = userinfodao;
}
}
4.2 service类，这里也是利用了all的思想，所以也有allservice的类
@Service
public class UserinfoService {
@Autowired
private AllDao alldao;
public int insertUserinfo(Userinfo user) {
return this.alldao.getUserinfodao().insertUserinfo(user);
}
public long userCount(Map pageMap) {
return this.alldao.getUserinfodao().userCount(pageMap);
};
public List selectPage(PageModel page) {
return this.alldao.getUserinfodao().selectPage(page);
}
public void deleteById(String id) {
this.alldao.getUserinfodao().deleteById(id);
}
public Userinfo queryById(String id){
return this.alldao.getUserinfodao().queryById(id);
};
public int updateById(Userinfo userinfo){
return this.alldao.getUserinfodao().updateById(userinfo);
};
public int updateBySelective(Userinfo userinfo){
return this.alldao.getUserinfodao().updateBySelective(userinfo);
};
}
@Service
public class AllService {
@Autowired
private UserinfoService userinfoservice;
public UserinfoService getUserinfoservice() {
return userinfoservice;
}
public void setUserinfoservice(UserinfoService userinfoservice) {
this.userinfoservice = userinfoservice;
}
}
4.3 下面就是我们的实现功能，对应的controller，这里有一个base，是用来声明service的，公共使用，所有的类都要继承它。
public class BaseController extends ActionSupport {
private AllService allservice;
public AllService getAllservice() {
return allservice;
}
public void setAllservice(AllService allservice) {
this.allservice = allservice;
}
}
功能的实现类：我这里的代码包括了分页的功能，也是自己写的，有需要的可以看看，要原码的在联系我。
@Transactional
/**
* 操作增删改查
* @author Administrator
*
*/
public class Insert extends BaseController {
cJson cjson = new cJson();
private String jsonString;
public String getJsonString() {
return jsonString;
}
public void setJsonString(String jsonString) {
this.jsonString = jsonString;
}
// 分页model
public PageModel page;
public String insert() {
try {
JSONObject object = JSONObject.fromObject(jsonString);
String name = object.getString("name");
String password = object.getString("password");
String sex = object.getString("sex");
String id = UUID.randomUUID().toString().replaceAll("-", "");
Date birthday = new SimpleDateFormat("yyyy-MM-dd").parse(object
.getString("birthday"));
String message = object.getString("message");
Userinfo user = new Userinfo(id, name, password, sex, birthday,
new Date(), message);
int ses = this.getAllservice().getUserinfoservice()
.insertUserinfo(user);
if (ses == 1) {
cjson.write("true");
}
} catch (IOException e) {
e.printStackTrace();
} catch (ParseException e) {
e.printStackTrace();
}
return null;
}
public String selectById() {
return null;
}
public String selectPage() {
try {
JSONObject object = JSONObject.fromObject(jsonString);
int gotoPage = object.getInt("gotoPage");
int pageNum = object.getInt("pageNum");
Map pageMap = new HashMap();
pageMap.put("sex", "男");
int userCount = (int) this.getAllservice().getUserinfoservice()
.userCount(pageMap);
page = new PageModel(userCount, pageNum, pageMap);
page.setGotoPage(gotoPage);
List userinfoList = this.getAllservice()
.getUserinfoservice().selectPage(page);
page.setList(userinfoList);
cjson.write(page);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
/**
* 根据id删除
*
* @return
*/
public String deleteById() {
try {
this.getAllservice().getUserinfoservice().deleteById(jsonString);
cjson.write("true");
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
/**
* 根据id查询
*
* @return
*/
public String queryById() {
try {
Userinfo userinfo = this.getAllservice().getUserinfoservice()
.queryById(jsonString);
cjson.write(userinfo);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
public String update() {
try {
JSONObject object = JSONObject.fromObject(jsonString);
String id = object.getString("userId");
String name = object.getString("name");
String password = object.getString("password");
String sex = object.getString("sex");
String bir = object.getString("birthday");
Date birthday = null;
if (bir != null && !bir.equals("")) {
birthday = new SimpleDateFormat("yyyy-MM-dd").parse(bir);
}
String message = object.getString("message");
Userinfo userinfo = new Userinfo(id, name, password, sex, birthday,
new Date(), message);
this.getAllservice().getUserinfoservice()
.updateBySelective(userinfo);
cjson.write("true");
} catch (ParseException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
对其中不懂的地方解释：cjson.write()是自己写的，其实是用的json传参，具体类：
public class cJson {
static HttpServletResponse response;
static PrintWriter out;
public void write(String jsonString) throws IOException {
String returnJSONObject = jsonString;
//System.out.println(returnJSONObject);
response = ServletActionContext.getResponse();
response.setCharacterEncoding("utf-8");
response.setContentType("text/htm;");
out = response.getWriter();
out.print(returnJSONObject);
out.flush();
out.close();
}
public void write(Object jsonObj) throws IOException {
String returnJSONObject = JSONArray.fromObject(jsonObj).toString();
//System.out.println(returnJSONObject);
HttpServletResponse response = ServletActionContext.getResponse();
response.setCharacterEncoding("utf-8");
response.setContentType("text/htm;");
PrintWriter out = response.getWriter();
out.print(returnJSONObject);
out.flush();
out.close();
}
}
5.下面是页面的功能
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
My JSP 'index.jsp' starting page
