SSM整合小Demo

SSM整合

数据库部分(Oracle)

1. 创建表

   CREATE TABLE product(
   id varchar2(32) default SYS_GUID() PRIMARY KEY,
   productNum VARCHAR2(50) NOT NULL,
   productName VARCHAR2(50),
   cityName VARCHAR2(50),
   DepartureTime timestamp,
   productPrice Number,
   productDesc VARCHAR2(500),
   productStatus INT,
   CONSTRAINT product UNIQUE (id, productNum)
   )
   

2. 添加数据

   insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice, productdesc, productstatus)
   values ('D71D9D079C224C749F8FC526DA39E7B7', 'junyang-002', '北京三日游', '北京', to_timestamp('10-10-2020 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1299, '不到北京非好汉', 1);
   insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice, productdesc, productstatus)
   values ('F4971A072D4C482196A39E219BCBF932', 'junyang-003', '上海七日游', '上海', to_timestamp('10-10-2020 11:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1599, '魔都,你值得来', 0);
   insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice, productdesc, productstatus)
   values ('058BBC3C69C54FADB14CFAD2517ACF48', 'junyang-003', '北京七日游', '北京', to_timestamp('05-01-2020 08:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 3000, '好好感受首都的魅力', 0);
   commit;

             }
         }						
         

   3. ssm_dao – com.junyang.ssm_dao

      1. 在pom.xml中添加依赖

      
      
          
              ssm
              com.junyang
              1.0-SNAPSHOT
          
          4.0.0
          
              
                  com.junyang
                  ssm_domain
                  1.0-SNAPSHOT
              
          
          ssm_dao
      
      
      
      

      2. 编写dao代码

         package com.junyang.ssm.dao;
         
         import com.junyang.ssm.domain.Product;
         import org.apache.ibatis.annotations.Select;
         import org.springframework.stereotype.Repository;
         
         import java.util.List;
         
         /**
          * 产品信息Dao
          */
         @Repository
         public interface ProductDao {
             /**
              * 查询所有产品信息
              * @return
              */
             @Select("select * from product")
             List findAll();
         }
         
         

   4. ssm_service – com.junyang.ssm_service

      1. pom.xml中添加依赖

         
         
             
                 ssm
                 com.junyang
                 1.0-SNAPSHOT
             
             4.0.0
         
             ssm_service
             
                 
                     com.junyang
                     ssm_dao
                     1.0-SNAPSHOT
                 
             
         
         
         

      2. 编写service代码

         package com.junyang.ssm.service;
         
         import com.junyang.ssm.domain.Product;
         import org.apache.ibatis.annotations.Select;
         import org.springframework.stereotype.Service;
         import org.springframework.transaction.annotation.Transactional;
         
         import java.util.List;
         
         public interface ProductService {
             /**
              * 查询所有信息
              * @return
              */
             @Select("select * from product")
             List findAll();
         }
         

      3. 创建impl包并编写service实现类ProductServiceImpl

         package com.junyang.ssm.service.impl;
         
         import com.junyang.ssm.dao.ProductDao;
         import com.junyang.ssm.domain.Product;
         import com.junyang.ssm.service.ProductService;
         import org.springframework.beans.factory.annotation.Autowired;
         import org.springframework.stereotype.Service;
         import org.springframework.transaction.annotation.Transactional;
         
         import java.util.List;
         @Transactional
         @Service
         public class ProductServiceImpl implements ProductService {
             @Autowired
             private ProductDao ProductDao;
             @Override
             public List findAll() {
                 return ProductDao.findAll();
             }
         }
         
         

   5. ssm_web – com.junyang.ssm_web

      1. pom.xml中添加依赖

         
         
         
             
                 ssm
                 com.junyang
                 1.0-SNAPSHOT
             
             4.0.0
         
             ssm_web
             war
             
                 UTF-8
                 1.8
                 1.8
             
         
             
                 
                     com.junyang
                     ssm_service
                     1.0-SNAPSHOT
                 
             
             
                 
                     
                         org.apache.tomcat.maven
                         tomcat7-maven-plugin
                         
                             8889
                         
         
                         2.2
                     
                 
             
         
         
         

      2. 编写controller代码

         package com.junyang.ssm.web;
         
         import com.junyang.ssm.domain.Product;
         import com.junyang.ssm.service.ProductService;
         import org.springframework.beans.factory.annotation.Autowired;
         import org.springframework.stereotype.Controller;
         import org.springframework.web.bind.annotation.RequestMapping;
         import org.springframework.web.servlet.ModelAndView;
         
         import java.util.List;
         
         @Controller
         @RequestMapping("/product")
         public class ProductController {
             @Autowired
             private ProductService ProductService;
             @RequestMapping("/findAll1")
             public void findAll1(){
                 List productList = ProductService.findAll();
                 for (Product product : productList) {
                     System.out.println(product);
                 }
             }
         }
         

2. 添加配置文件 – 在ssm_webresources下创建

   1. applicationContext.xml

   2. db.properties

      jdbc.driver=oracle.jdbc.driver.OracleDriver
      jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
      jdbc.username=C##ssm
      jdbc.password=root
      

   3. spring-mvc.xml

   4. 修改web.xml

      
      
      
        
        
          contextConfigLocation
          classpath*:applicationContext.xml
        
      
        
        
          org.springframework.web.context.ContextLoaderListener
        
        
        
          org.springframework.web.context.request.RequestContextListener
        
      
        
        
          dispatcherServlet
          org.springframework.web.servlet.DispatcherServlet
          
          
            contextConfigLocation
            classpath:spring-mvc.xml
          
          
          1
        
        
          dispatcherServlet
          /
        
      
        
        
          characterEncodingFilter
          org.springframework.web.filter.CharacterEncodingFilter
          
            encoding
            UTF-8
          
        
        
          characterEncodingFilter
          /*
        
      
        
          index.html
          index.htm
          index.jsp
          default.html
          default.htm
          default.jsp
        
      
      
      

   5. 日志记录文件

      # Set root category priority to INFO and its only appender to CONSOLE.
      #log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
      log4j.rootCategory=debug, CONSOLE, LOGFILE
      
      # Set the enterprise logger category to FATAL and its only appender to CONSOLE.
      log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE
      
      # CONSOLE is set to be a ConsoleAppender using a PatternLayout.
      log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
      log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
      log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
      
      # LOGFILE is set to be a File appender using a PatternLayout.
      # log4j.appender.LOGFILE=org.apache.log4j.FileAppender
      # log4j.appender.LOGFILE.File=d:\axis.log
      # log4j.appender.LOGFILE.Append=true
      # log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
      # log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
      
      
      

   6. 创建index.jsp

      <%@ page language="java" contentType="text/html; charset=UTF-8"
               pageEncoding="UTF-8"%>
      
      
          点击超链接查询所有商品信息
      
      
      
      

   7. 使用父工程maven项目的install命令.

   8. 配置maven
      

   9. 启动,浏览器输入项目地址,访问到首页.点击index中的连接,观察控制台输出.
