SSM案例-企業權限系統（3）- 產品操作

1 新建實體類

2 DAO

3 Service

package com.tzb.service;

import com.tzb.domain.Product;

import java.util.List;

public interface IProductService {
    public List<Product> findAll();
}

package com.tzb.service.impl;

import com.tzb.dao.IProductDao;
import com.tzb.domain.Product;
import com.tzb.service.IProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

@Service("productService")
@Transactional
public class ProductServiceImpl implements IProductService {

    @Autowired
    private IProductDao productDao;

    @Override
    public List<Product> findAll() {
        return productDao.findAll();
    }
}

    private IProductService productService;

    @RequestMapping("/findAll.do")
    public ModelAndView findAll(){
        ModelAndView mv = new ModelAndView();
        List<Product> ps = productService.findAll();
        mv.addObject("productList",ps);
        mv.setViewName("product-list");
        return mv;
    }
}

6 添加 jsp 等頁面

7 運行方法一

在 web模塊 pom.xml 添加 tomcat 插件

   <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <configuration>
                    <port>8080</port>
                </configuration>
                <version>2.2</version>
            </plugin>
        </plugins>

8 運行方式二

https://blog.csdn.net/tyl36908/article/details/82630394
研發環境只有web模塊一個war exploded包可選，配置好tomcat啓動後查看發佈包裏面內容依賴的幾個子模塊的class及配置文件均未打包進去進行發佈。
