025 SSM简单搭建
参考了同事的文档，自己也写一篇文档。
同时，补充了一下，程序是如何运行的。
一：SSM框架
1.说明
SSM（Spring+SpringMVC+MyBatis）框架集由Spring、SpringMVC、MyBatis三个开源框架整合而成，常作为数据源较简单的web项目的框架。
2.每个框架的功能
其中spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。
SpringMVC分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。
MyBatis是一个支持普通SQL查询，存储过程和高级映射的优秀持久层框架。
页面发送请求给控制器，控制器调用业务层处理逻辑，逻辑层向持久层发送请求，持久层与数据库交互，后将结果返回给业务层，业务层将处理逻辑发送给控制器，控制器再调用视图展现数据。
二：新建项目
1.程序大纲
2.使用软件
IDEA
3.新建Maven项目
4.定位
5.设置maven
6.项目保存路径
三：到目前为止的效果
1.大纲
2.配置tomcat
3.clean install
4.运行效果
很奇怪，啥时候定位到index.jsp的呢。这个以后再研究。
5.web.xml
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app>
<display-name>Archetype Created Web Application</display-name>
</web-app>
6.pom.xml
这个pom感觉有点繁。不过现在是生成的，就先原本粘贴了。

五：开始创建MVC目录
1.原目录
2.在main节点下新建java和resource
在main上右键后，使用New Folder新建。
3.设置java与resource类型
4.创建如下java项目目录
只需要新建package就可以了。
action：存放Controller
dao：sql对应的接口
mapper：sql的xml文件
model：数据库实体类
service：就是service了
5.创建resource下的文件
先新建一个config目录，以及ssm需要的三个配置文件。
注意的是config不是package，是Directory。
spring的配置文件applicationContext.xml
spring MVC的配置文件springmvc-servlet.xml
数据库链接的配置文件jdbc.properties
六：配置文件以及web.xml的内容
1.applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>

七：对应关系（拷贝）
1.对应关系理解
八：测试程序
1.大纲
2.新建数据库
sql如下：
CREATE TABLE
student
(
id INT(1),
name VARCHAR(20),
sex TINYINT(1),
address VARCHAR(50)
)
插入数据：
INSERT INTO student VALUES ('1', 'tom', '1', '1');
3.运行
输入网址：
http://localhost:8080/Hello/SayHello
4.效果
以后再做解析。
九：Java区域的程序
1.Student.java
几个字段的domain。
package model;
import java.io.Serializable;
public class Student implements Serializable {
private static final long serialVersionUID = 1L;
private int id;
private String name;
private boolean sex;
private String address;
public void setId(int id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
public void setSex(boolean sex) {
this.sex = sex;
}
public void setAddress(String address) {
this.address = address;
}
public int getId() {
return id;
}
public String getName() {
return name;
}
public boolean isSex() {
return sex;
}
public String getAddress() {
return address;
}
@Override
public String toString() {
return "Student{" +
"id=" + id +
", name='" + name + '\'' +
", sex=" + sex +
", address='" + address + '\'' +
'}';
}
}
2.StudentDao.java
这个没有用到，dao的处理在service中处理了
package dao;
import model.Student;
public interface StudentDao {
/** 方法名对应Mapper中方法名 */
// public Student getStudent(int id);
}
3.StudentService.java
package service; import model.Student;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller; @Controller
public class StudentService {
/**
*sqlSessionTemplate模板提供了sqlsession
*/
@Autowired
private SqlSessionTemplate sqlSessionTemplate;
public Student getStudent(int id) {
Student student = sqlSessionTemplate.selectOne("dao.StudentDao.getStudent", id);
return student;
}
}
4.HelloWorld.java
package action; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import service.StudentService; @Controller
@RequestMapping("/Hello")
public class HelloWorld {
@Autowired
private StudentService studentService; @RequestMapping("/SayHello")
public String SayHello(Model model) {
String student = studentService.getStudent(1).toString();
System.out.println(student);
model.addAttribute("message", student);
// 对应页面名
return "/hello";
}
}
5.StudentMapper.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="dao.StudentDao"> <select id="getStudent" parameterType="int" resultType="model.Student">
SELECT *
FROM student
WHERE id = #{id}
</select> </mapper>
十：在过程中遇到的几个奇葩的问题
1.缺少common-pool

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
Sat Jul 21 23:16:04 CST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
