Spring-Jsf2.0-Mybatis整合（可運行工程）

學習了半個月的Spring 、 JSF2.0（使用Primefaces）以及Mybatis，今天來個整理，希望對以後有所幫助！

1）我用的是maven項目，所以jar 包以及jar包的版本都由pom文件決定，相關內容如下：

如下圖：

2）整個工程的包構造如下：

3）配置web.xml

<?xml version="1.0" encoding="UTF-8" ?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

</welcome-file-list>
</web-app>

4）編寫基本類

個人覺得，自己的設置是嚴重問題的，但是只是爲了測試，所以就沒把心思放在這裏了，
首先我的EntityBean 與 BackBean整合在一起了，這個是一個大問題。當然後面我又重構了一下，添加了一個DataBean，這個Bean是一個BackBean，把User當成他的EntityBean來處理了。好吧，下面我從整合Mybatis開始說起，也是使用mybatis的新特性，
首先是EntityBean的編寫：
public class User implements Serializable {
private static final long serialVersionUID = 1L;
private String id;
private String name;
private String password;
//get set 方法必須添加
}
如下進行接口的編寫：
public interface IUserDao {
public List<User> selectUserByName(String name);
public User selectUserByUser(User user);
public void updateUser(User user);
public void deleteUser(User user);
public void insertUser(User user);
}
對應userMapper.xml文件
/* 這裏尤其要注意，因爲Mybatis自動幫我們完成接口與映射文件的配對，並且編寫實現代理類，所以命名是有要求的，如方法名與id是一一對應的*/
<?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.changxin.dao.user.IUserDao">

<resultMap type="User" id="userResultMap">
<id column="u_id" property="id" />
<result column="u_name" property="name" />
<result column="u_password" property="password" />
</resultMap>

<select id="selectUserByName" parameterType="java.lang.String"
resultMap="com.changxin.dao.user.IUserDao.userResultMap">
select
u_id ,
u_name ,
u_password
from users
<where>
<if test="_parameter != null">u_name like '%${_parameter}%'</if>
</where>
</select>
<select id="selectUserByUser" parameterType="User"
resultMap="com.changxin.dao.user.IUserDao.userResultMap">
select
u_id ,
u_name ,
u_password
from users
<trim prefix="where" prefixOverrides="and|or">
<choose>
<when test="id != null ">u_id = #{id}</when>
<when test="name != null and password !=null">u_name like #{name} and u_password like #{password}</when>
<when test="name != null and password == null">u_name like #{name}</when>
</choose>
</trim>
</select>
<update id="updateUser" parameterType="User">
update users
<set>
<if test="name != null">u_name=#{name},</if>
<if test="password != null">u_password=#{password},</if>
</set>
where u_id = #{id}
</update>
<delete id="deleteUser" parameterType="User">
delete from users where
u_id = #{id}
</delete>

<insert id="insertUser" parameterType="User" >
insert into users(u_name,u_password)
values(#{name},#{password})
</insert>
</mapper>

5）配置SqlConfig.xml
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

<typeAliases>
<typeAlias type="com.changxin.model.User" alias="User"/>
</typeAliases>
</configuration>

6）配置applicationContext.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
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/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd "
>
<!—配置數據源-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
<property name="jdbcUrl"
value="jdbc:sqlserver://localhost:1433;databaseName=Testdb"></property>
<property name="user" value="sa"></property>
<property name="password" value="123"></property>
<property name="checkoutTimeout" value="30000" />
<property name="maxPoolSize" value="30"></property>
<property name="initialPoolSize" value="10" />
</bean>
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!—配置註解式事務-->
<tx:annotation-driven transaction-manager="transactionManager" />
<!—這裏使用Mybatis-Spring註解方式完成daoImpl的編寫，所以我們只需要聲明接口不需要寫實現類，這也是Spring的好處 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:config/Sqlconfig.xml" />
<property name="mapperLocations" value="classpath*:com/changxin/sqlmap/*Mapper.xml" />
</bean>
<!—找到所有需要進自動注入的文件，mapper文件 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.changxin.dao.user" />
</bean>
<!—配置service類，這個是必須配置的，因爲後面BackBean還需要引用他作爲自己的屬性，但是他引用dao層的屬性是通過註解自動注入的，下面就看看service如何編寫 -->
<bean id="userService" class="com.changxin.service.user.UserService">
</bean>

</beans>

7）如下編寫service層代碼

@Transactional
public class UserService {
@Autowired //這個註解會使spring自動完成注入，他是對應接口的實現代理類
private IUserDao userDao = null;

public List<User> selectUserByName(String name) {
return userDao.selectUserByName(name);
}

public User selectUserByUser(User user) {
return userDao.selectUserByUser(user);
}

public void updateUser(User user) {
userDao.updateUser(user);
}

public void deleteUser(User user) {
userDao.deleteUser(user);
}

public void insertUser(User user) {
userDao.insertUser(user);
}

public IUserDao getUserDao() {
return userDao;
}

public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}

}

8）編寫BackBean
@ManagedBean(name = "dataBean") //註解方式代替faces-config中managedBean的編寫
@SessionScoped //採用session生命週期
public class DataBean implements Serializable {
@ManagedProperty(value="#{userService}") //applicationContext.xml配置service注入
private UserService userService;
private List<User> users;
private User user;
private User tempUser;
private User tableUser;
private boolean rendFlag;
private boolean rendFlag2;

public DataBean() {
user = new User();
}

public void init(){
users = userService.selectUserByName(null);
}

/* 自己編寫校驗器*/
public void validate(FacesContext context, UIComponent component, Object obj)
throws ValidatorException {
String password = (String) obj;

if (password.length() < 6) {
FacesMessage message = new FacesMessage(
FacesMessage.SEVERITY_ERROR, "字符長度小於6", "字符長度不得小於6");
throw new ValidatorException(message);
}

if (!password.matches(".+[0-9]+")) {
FacesMessage message = new FacesMessage(
FacesMessage.SEVERITY_ERROR, "密碼必須包括字符與數字", "密碼必須是字符加數字所組成");
throw new ValidatorException(message);
}
}

public boolean validate(User vUser){
boolean flag = true;
if("".equals(vUser.getName().trim())){
flag = false;
}
if("".equals(vUser.getPassword().trim())){
flag = false;
}
return flag;
}

/**
*
* 控制用戶登錄後的頁面流程，根據返回值找頁面，沒有路徑默認爲根路徑下的文件
*/
public String login() {
String result = "message.xhtml";
if(validate(user)){
User u = userService.selectUserByUser(user);
if(u == null)
{
result = "login.xhtml";
}else{
init();
}
}
return result;
}

public void prefInsertUser(ActionEvent event){
tempUser = new User();
rendFlag = false;
rendFlag2 = true;

}
public void prefUpdateUser(ActionEvent event){
if(tableUser != null){
rendFlag = true;
rendFlag2 = false;
}
}
public void insertUser(ActionEvent event){
if(validate(tempUser)){
userService.insertUser(tempUser);
cancel(null);
init();
}
}
public void updatetUser(ActionEvent event){
if(validate(tableUser)){
userService.updateUser(tableUser);
cancel(null);
init();
}
}

public void deleteUser(ActionEvent event){
if(tableUser != null){
userService.deleteUser(tableUser);
init();
cancel(null);
}
}

public void cancel(ActionEvent event){
this.rendFlag = false;
this.rendFlag2 = false;
this.tempUser = null;
this.tableUser = null;
}
//get set 很重要

9）配置faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-facesconfig_2_1.xsd"
version="2.1">

11）整個配置就已經完成了，測試的話還需要寫對應的數據庫，寫完之後就可以部署到tomcat運行了，不過我的pom文件寫了jetty插件，所以，一種更好的方式是使用命令： jetty:run
運行服務器，然後訪問，但是又有問題，那就是jetty當前版本並不支持jsf2.0這種註解方式，所以你自己選擇吧！

12）休息了……………….
