第一次整合，记录一下。

一、相关配置

1、先看下整体目录吧


2、pom.xml文件配置

			<value>UTF-8</value>
		</property>
	</bean> 
	<mvc:annotation-driven></mvc:annotation-driven>
	<mvc:default-servlet-handler/>
</beans>

9、测试javabean

public class User {

	private String id;
	private String name;
	private String password;
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + ", password=" + password + "]";
	}		
}


10、测试controller 

@Controller
public class UserContorller {

	@Resource
	private UserService userService;
	
	@RequestMapping("/user")
	public String getUser(Map<String,Object> map)
	{
		User user = userService.queryUser().get(0);
		map.put("user", user);
		map.put("time", new Date());
		System.out.println("user ---"+user);
		return "success";
	}
}

11、测试service

public interface UserService {

	
	public List<User> queryUser();
	
}
@Service("userService")
public class UserServiceImpl implements UserService {

	@Resource
	private UserDao userDao;
	
	public List<User> queryUser() {
		System.out.println("UserServiceImpl queryUser");
		return userDao.queryUser();
	}

}

12、测试dao

public interface UserDao {

	public List<User> queryUser();
	
}

13、测试mapper

<?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.cjl.dao.UserDao">
<select id="queryUser" resultType="User">
	select * from user
</select>
</mapper>
14、success.jsp 
<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8" isELIgnored="false"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
request user:${requestScope.user }
<br><br>
time:${requestScope.time}
</body>
</html>
注意：用requestScope.user 一定要把el表达式开关打开：isELIgnored="false"

15、结果


二、整合中出现的问题

1、maven 下载 commons-fileupload.jar 死活下载不下来

解决办法：换镜像

找到maven仓库中settings.xml文件，找到<mirrors>，添加以下代码

 <mirror>
      <id>alimaven</id>
      <name>aliyun maven</name>
      <url>
          http://maven.aliyun.com/nexus/content/groups/public/
      </url>
      <mirrorOf>central</mirrorOf>        
    </mirror>

2、
①、org.xml.sax.SAXParseException;必须声明元素类型 "configuraation"


②、org.xml.sax.SAXParseException 文档根元素 "mapper" 必须匹配 DOCTYPE 根 "configuraation"

原因是，我的mybatis-config.xml文件错误，如下图所示：


报第一个错误，然后我把 DOCTYPE后面的configuraation改正确了，但是没发现下边的标签也是错误的，没有修改，又报第二个错误，才发现标签中也是错误的。正确如下：


所以，以后不要手敲了，还是复制粘贴靠谱。

3、

java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException

缺少aspectj jar包：

 <dependency>
    	<groupId>org.aspectj</groupId>
    	<artifactId>aspectjweaver</artifactId>
    	<version>1.6.12</version>
    </dependency>

4、在eclipse .properties文件中写中文

安装插件即可，步骤如下：

https://blog.csdn.net/liyys/article/details/70244093

①、点击 help--Install New Software

②、在打开的窗口点击 add 按钮，

③、在Location 栏输入  http://propedit.sourceforge.jp/eclipse/updates/  然后点击ok

④、在出现的列表中，选择选择PropertiesEditor，然后Next.

⑤、点击“ I accept...........”然后Finish，然后等待安装

⑥、安装完成后点击“Restart Now”重启eclipse

⑦、此时在properties文件上点右键，点击“Open With"-"PropertiesEditor"，打开文件，现在就可以直接输入中文了

5、Access denied for user 'ThinkPad'@'localhost' (using password: YES)
Access denied for user 'cjl'@'localhost' (using password: YES)

这样的链接错误，全是jdbc.properties文件 和 applicationContext.xml 中关于数据连接那段两边不一致或者粗心配置错误导致的。另外：jdbc.properties 中的属性最好加上前缀

6、java.lang.UnsupportedOperationException

这个错误是因为mapper中的查询方法返回类型配置错误的原因，dao方法，查询所有用户，返回的list，

所以我就这样配置了resultType="list"，然后报错，正确的应该是resultType="User"。粗心啊。

注意：resultType返回的是集合中的元素类型，而不是集合本身
