1.在camel-manger-web中配置mybatis resource spring

mybatis包下
SqlMapConfig.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>
    <!-- 配置分页插件    拦截器-->
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageHelper">
            <!-- 设置数据库类型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库-->        
            <property name="dialect" value="mysql"/>
        </plugin>
    </plugins>
</configuration>

resource包下 db.properties resource.properties

db.properties 配置数据库

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/taobao?characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

resource.properties

因为 image.png

所以在src/main/java下 新建一个名字叫com.camel.controller的包

数据库

新建数据库名字叫e3mall

导入sql

6.2. Mybatis逆向工程

使用mybatis官方提供的mybatis-generator生成pojo、mapper接口及映射文件。
并且将pojo放到e3-manager-pojo工程中。
将mapper接口及映射文件放到e3-manager-dao工程中。
6.7. 整合测试
6.7.1. 需求
根据商品id查询商品信息，返回json数据。

6.7.2. Dao层
由于是单表查询可以使用逆向工程生成的代码。

6.7.3. Service层
参数：商品id
返回值：TbItem
业务逻辑：根据商品id查询商品信息。
camel.manager.service 包下ItemService.java 创建接口

package camel.manager.service;

import camel.dspt.manager.pojo.TbItem;

public interface ItemService {
    //根据商品查id

    TbItem getItemById(long id);
}

ItemServiceImpl.java 实现类

package imp;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import camel.dspt.manager.pojo.TbItem;
import camel.dspt.manager.pojo.TbItemExample;
import camel.dspt.manager.pojo.TbItemExample.Criteria;
import camel.manager.mapper.TbItemMapper;
import camel.manager.service.ItemService;
@Service
public class ItemServiceImpl implements ItemService{
@Autowired
    private TbItemMapper tbItemMapper;
    @Override
    public TbItem getItemById(long id) {
//      TbItem tbItem=  tbItemMapper.selectByPrimaryKey(id);
        //按条件查询
        TbItemExample example=new TbItemExample();
        Criteria  criteria=example.createCriteria();
        //设置查询条件
        criteria.andIdEqualTo(id);
        List<TbItem> list=tbItemMapper.selectByExample(example);
        if(list!=null &&list.size()>0){
            return list.get(0);
        }
        return null;
    }

}

在camel-manger-web工程下 com.camel.controller 创建ItemController.java

package com.camel.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import camel.dspt.manager.pojo.TbItem;
import camel.manager.service.ItemService;

@Controller
public class ItemController {
@Autowired
    private ItemService itemService;
@RequestMapping("/item/{itemId}")
@ResponseBody
private TbItem getItemById(@PathVariable Long itemId) {
    TbItem tbItem = itemService.getItemById(itemId);
    return tbItem;

}
}

测试

点击向下的箭头 选择RUN Configurations

Maven Waring : Version is duplicate of parent version

问题描述：

新项目在创建的时候，因为用到了分模块的，所以导致子模块的pom文件，报了 如下警告：

image image

解决办法：

直接 Window --> Preferences --> Maven --> Errors/Warnings --> Ignore 将两个警告，调成忽略即可解决。 如下图所示：

image

在camel-dspt-manager的聚合工程 选择pom.xml


image.png image.png
运行后 出现java.net.BindException: Address already in use: JVM_Bind :8080解决方法

端口冲突

根据异常图，判断问题为端口冲突


image.png

1.按Windows键+R，输入cmd，进入命令行模式，如下图所示


image.png

2.cmd命令模式下输入cd c:\windows\system32进入到系统文件夹下，输入netstat -ano，然后找到占用8080端口的那个进程 如下图所示

image.png image.png

3.PID号为1488的进程占用着8080端口，打开任务管理器查看详细信息，查找PID号为1488进程，点击结束任务即可，如下图所示


image.png

4.重新启动想启动的应用

效果截图：
