2.SpringhibernateStudy-servlet.xml? 主要對(duì)mvc web層的javabean定義
注意：這里名稱要與在web.xml中對(duì)org.springframework.web.servlet.DispatcherServlet的對(duì)應(yīng)servlet名稱對(duì)應(yīng)。
這里web.xml文件里配置了名字為SpringhibernateStudy，所以文件名必須為：SpringhibernateStudy-servlet.xml
格式：servlet名稱+-servlet.xml?
如果配置名稱為SpringServlet則，配置文件應(yīng)該為：SpringServlet-servlet.xml
內(nèi)容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN/EN" "<!--? - Application context definition for "springapp" DispatcherServlet.? -->
<beans>?
? <!-- 下面定義web層控制器類，引用到業(yè)務(wù)處理類，通過(guò)已經(jīng)定義的service類來(lái)自動(dòng)注入web控制器引用的service類-->

?<property name="mappings">?????
??<props>
???<prop key="/user.do">UserController</prop>
???
??? <!-- 這里表示 //user.do會(huì)由 名稱為UserController的對(duì)應(yīng)的控制器來(lái)apps.hibernatetest.ioc.UserController處理-->
??</props>
?</property>
?? </bean>
?
</beans>??
?
?
2.hibernate配置文件：
這里主要是映射文件 ：User.hbm.xml 與表USER_TABLE 對(duì)應(yīng)
名稱為：User.hbm.xml?
詳細(xì)配置代碼如下：
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping
??? PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
??? "<hibernate-mapping>
??? <class name="apps.hibernatetest.ioc.User" table="USER_TABLE">
?????? <id name="id" type="string" unsaved-value="null">
?????????? <column name="ID" sql-type="varchar2(255)" not-null="true" />
?????????? <generator class="uuid.hex"/>
?????? </id>
?????? <property name="username" type="string">
?????????? <column name="USERNAME" sql-type="varchar2(20)"/>
?????? </property>
????? <property name="password" type="string">
?????????? <column name="PASSWORD" sql-type="varchar2(20)"/>
?????? </property>
??? </class>
</hibernate-mapping>
注意：
1.類名一定要寫完整路徑帶包名
2.對(duì)應(yīng)的數(shù)據(jù)庫(kù)表明一定要與數(shù)據(jù)庫(kù)一致
?? 如： <class name="apps.hibernatetest.ioc.User" table="USER_TABLE">
???
??? name屬性為：實(shí)體類名
??? table屬性為：數(shù)據(jù)庫(kù)表的名稱
???
3.其字段信息要與數(shù)據(jù)庫(kù)表結(jié)構(gòu)一致
4.該配置文件放在與實(shí)體類相同的目錄中，并在spring文件中給與說(shuō)明
?????????? 如：User.java的完整路徑為apps.hibernatetest.ioc.User,對(duì)應(yīng)配置如下
? ??<property name="mappingResources">
? ???<list>
? ????<value>apps/hibernatetest/ioc/User.hbm.xml</value>
? ???</list>
? ??</property>
?
用hibernate往數(shù)據(jù)庫(kù)里插入數(shù)據(jù)時(shí)，出現(xiàn)net.sf.hibernate.MappingException: No persister for的解決辦法
根據(jù)我的出錯(cuò)處理經(jīng)驗(yàn)，出現(xiàn)No persister for錯(cuò)誤后有如下三種解決辦法：
1》檢查hbm.xml文件。
2》檢查cfg.xml文件，看看類的hbm.xml文件名是不是已經(jīng)寫上了。
3》對(duì)于one-to-many（Parent-to-Child）的關(guān)系，應(yīng)該是
child.setParent(parent)，而不是child.setParent(parent.id)
???
???
3. web.xml文件：
這里對(duì)servlet等信息配置：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "<web-app>
?
? <listener>
??? <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
? </listener>
? <servlet>
?
??? <servlet-name>ContextLoaderServlet</servlet-name>
??? <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
??? <load-on-startup>1</load-on-startup>
? </servlet>
?
?
???? <!-- 上面定義監(jiān)聽(tīng)器和上下文裝載的servelet,來(lái)裝載applicatincontext.xml文件 -->
?
?
?
???? <!-- 下面定義配置Spring的請(qǐng)求分發(fā)器類-->
? <servlet>
??? <servlet-name>SpringhibernateStudy</servlet-name>
??? <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
??? <load-on-startup>2</load-on-startup>

??? <load-on-startup>3</load-on-startup>
? </servlet>
?
???? <!-- 下面定義配置Spring的請(qǐng)求分發(fā)器將處理所有*.do的請(qǐng)求-->
? <servlet-mapping>

??? <url-pattern>*.jsp</url-pattern>
? </servlet-mapping>
</web-app>
六、相關(guān)各個(gè)類的詳細(xì)代碼極其說(shuō)明
1. User.java? 表示用戶實(shí)體的值對(duì)象類，與數(shù)據(jù)庫(kù)用戶表結(jié)構(gòu)相對(duì)應(yīng)，標(biāo)準(zhǔn)的javabean,提供setter和getter方法。
注意：
1.提供setter和getter方法，符合javabean規(guī)范
2.實(shí)現(xiàn)java.io.Serializable可序列化接口。
3.與數(shù)據(jù)庫(kù)表結(jié)構(gòu)一一對(duì)應(yīng)
User.java
package apps.hibernatetest.ioc;
public class User implements java.io.Serializable
{
??????????? private String id;
??????????? private String username;
??????????? private String password;
??????????? public User(){}
??????????? public String getId()
??????????? {
????????????????????? return id;
??????????? }
??????????? public void setId(String id)
??????????? {
????????????????????? this.id = id;
??????????? }
??????????? public String getUsername()
??????????? {
????????????????????? return username;
??????????? }
??????????? public void setUsername(String username)
??????????? {
???????????????????? this.username = username;
??????????? }
??????????? public String getPassword()
??????????? {
????????????????????? return password;
??????????? }
??????????? public void setPassword(String password)
??????????? {
????????????????????? this.password = password;
??????????? }
}
?
2. UserDAO.java? DAO接口
UserDAO.java
package apps.hibernatetest.ioc;
public interface UserDAO
{
??? public void userAdd(User user);
}
?
?
3. UserDAOImp.java? DAO接口的實(shí)現(xiàn)類
注意：
1. 繼承HibernateDaoSupport
2. 實(shí)現(xiàn)dao接口
3.使用模板類處理數(shù)據(jù)
UserDAOImp.java
package apps.hibernatetest.ioc;
import net.sf.hibernate.HibernateException;
import net.sf.hibernate.Query;
import net.sf.hibernate.Session;
import org.springframework.orm.hibernate.HibernateCallback;
import org.springframework.orm.hibernate.support.HibernateDaoSupport;
public class UserDAOImp extends HibernateDaoSupport? implements UserDAO
{
? public void userAdd(User user)
? {
??????? //try
?????? // {
??????????? //System.out.println("save="+getHibernateTemplate().save(user));
??????????? System.out.println("aaa====>"+user.getUsername());
??????????? System.out.println("bbb====>"+user.getPassword());
??????????? getHibernateTemplate().save(user);
??????????? System.out.println("bbb");
?????? /* }
??????? catch(Exception? e)
??????? {
???????????? System.out.println("執(zhí)行插入用戶錯(cuò)誤！");
??????? }*/
? }
?
}
?
4. UserService?? 業(yè)務(wù)邏輯層的接口
UserService.java
package apps.hibernatetest.ioc;
public interface UserService
{
? public void userAdd(User user);
}
5. UserServiceImp 業(yè)務(wù)邏輯層的接口的實(shí)現(xiàn)類，調(diào)用DAO接口實(shí)現(xiàn)業(yè)務(wù)邏輯。
注意：
1.實(shí)現(xiàn)指定的service接口
2.接口實(shí)現(xiàn)調(diào)用DAO接口
3.必須有userDAO屬性，并提供setter方法，如下
? private UserDAO userDAO;
? public UserDAO getUserDAO()
? {
??????? return userDAO;
? }
? public void setUserDAO(UserDAO userDAO)
? {
??????? this.userDAO = userDAO;
? }
?
? 在配置文件中，通過(guò)配置自動(dòng)實(shí)現(xiàn)DAO屬性的自動(dòng)注入。
?
? 通過(guò)這樣來(lái)定義service業(yè)務(wù)類和DAO的依賴關(guān)系
?
?
UserServiceImp.java
package apps.hibernatetest.ioc;
public class UserServiceImp implements UserService
{
? private UserDAO userDAO;
? private User user = new User();
? public UserDAO getUserDAO()
? {
??????? return userDAO;
? }
? public void setUserDAO(UserDAO userDAO)
? {
??????? this.userDAO = userDAO;
? }
? public void userAdd(User user)
? {
????? userDAO.userAdd(user);
? }
}
?
6. UserController web層客戶調(diào)用層，調(diào)用業(yè)務(wù)邏輯層，實(shí)現(xiàn)對(duì)業(yè)務(wù)邏輯的處理。（前臺(tái)）
UserController.java
package apps.hibernatetest.ioc;
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.*;
import javax.servlet.http.*;
import org.springframework.web.bind.RequestUtils;
import java.io.IOException;
import java.util.Map;
import java.util.*;
import java.util.HashMap;
import org.apache.commons.beanutils.BeanUtils;
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
public class UserController implements Controller
{
? private UserService userService;
? public void setUserService(UserService userService)
? {
??????? this.userService = userService;
? }
? public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
?{
??????????? String url="";
??????????? url="addok.jsp";
??????????? User u=new User();
??????????? u.setUsername("aaa");
??????????? u.setPassword("bbbb");
??????????? userService.userAdd(u);
??????????? return new ModelAndView(url);
?}
}
注意：
1.實(shí)現(xiàn)Controller接口
2.提供私有屬性，并提供setter方法
如下代碼
? private UserService userService;
? public void setUserService(UserService userService)
? {
??????? this.userService = userService;
? }
?
?3.在控制器在handleRequest中調(diào)用屬性u(píng)serService調(diào)用業(yè)務(wù)邏輯。
?
?
??????????? User u=new User();
??????????? u.setUsername("aaa");
??????????? u.setPassword("bbbb");
??????????? userService.userAdd(u);
???????????
4. 定義url變量，設(shè)置其值，作為ModelAndView類的構(gòu)造函數(shù)的參數(shù)，作為業(yè)務(wù)邏輯處理完后的跳轉(zhuǎn)地址
??????????? String url="";
??????????? url="addok.jsp";
??????????? return new ModelAndView(url);
???????????
???????????
?
???????????
???????????

九、在main方法中對(duì)在配置文件中的javabean類方法測(cè)試的代碼：
注意：applicationContext.xml文件放在classes根目錄下
