一. 添加依赖
在整合之前，我们先来看一下，如果不适用Maven，我们应该如何将ssm整合，如果您想查看使用Maven整合SSM，请直接打开本文第五段
二. Spring 整合SpringMVC
1. Spring配置文件：applicationContext.xml
-
配置自动扫描组件，不扫描控制层的组件
2. SpringMVC的配置文件：spring-mvc.xml
-
配置自动扫描组件，只扫描控制层的组件
-
视图解析器
-
静态资源访问
3. web.xml
-
处理乱码的过滤器：CharacterEncodingFilter
-
请求分配器：初始化SpringMVC的IOC容器，DispatchServlet
-
上下文监听：初始化Spring的IOC容器，ContextLoaderListener
三. 整合Mybatis
1. 配置mybatis-config.xml
2. 配置jdbc.properties
3. 配置log4j.properties
4. 添加BookMapper.xml
5. 修改applicationContext.xml
-
配置DruidDataSource
-
配置DataSourceTransactionManager
-
配置开启使用注解配置事务
-
配置SQLSessionFactoryBean
-
配置MapperScannerConfigurer
四. 代码文件
1. 数据库
数据库采用的还是 《MyBatis：简单使用》一文中创建的数据库
2. Book
package io.zhangjia.ssm.entity;
public class Book {
private Integer bookId;
private String name;
private String author;
private Double price;
public Integer getBookId() {
return bookId;
}
public void setBookId(Integer bookId) {
this.bookId = bookId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
public Double getPrice() {
return price;
}
public void setPrice(Double price) {
this.price = price;
}
@Override
public String toString() {
return "Book{" +
"bookId=" + bookId +
", name='" + name + '\'' +
", author='" + author + '\'' +
", price=" + price +
'}';
}
}
3. Controller
package io.zhangjia.ssm.controller;
import io.zhangjia.ssm.entity.Book;
import io.zhangjia.ssm.mapper.BookMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class TestController {
@Autowired
private BookMapper bookMapper;
@GetMapping("/test")
public String Test(Integer id, Model model) {
Book book = bookMapper.queryById(id);
model.addAttribute("book",book);
System.out.println("book = " + book);
return "test";
}
}
4. BookMapper
package io.zhangjia.ssm.mapper;
import io.zhangjia.ssm.entity.Book;
public interface BookMapper {
Book queryById(Integer bookId);
}
5. Service
package io.zhangjia.ssm.service;
import org.springframework.stereotype.Service;
@Service
public class TestService {
}
6. BookMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper

五. 使用Maven整合SSM
使用Maven整合SSM非常简单，首先按照本站《Maven：使用IDEA基于Maven创建JavaWeb项目》一文的教程创建JavaWeb项目，
并将pom.xml的内容替换为：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

接下来将上文前四节中所有文件，按照下图的方式，分为放入指定文件夹即可完成ssm的整合
