使用eclipse搭建ssm(Spring+SpringMVC+Mybatis)框架專案附原始碼

第一步:開啟eclipse,單擊右鍵–》new–》Dynamic Web Project,輸入專案名稱後一直點選next到最後一步,勾選建立web.xml後點擊finish,主要的目錄為圖中選中的三部分。

第二步:複製spring、springmvc和mybatis的jar包加入到lib目錄中,選中所有jar包右鍵BuildPath->add Build Path

這裡寫圖片描述

第三步:在web.xml中新增spring的監聽器,springmvc的前端控制器
<?xml version="1.0" encoding="UTF-8"?>

第三步:建立包目錄結構和相關的配置檔案

    <mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven>

            </set>
        </property> -->
    </bean>


</beans>

SqlMapConfig.xml為只含有configuration標籤的空檔案,負責配置一些全域性資訊

第四步:編寫DemoController、Demo、DemoService、DemoMapper檔案

DemoController.java

@Controller
@RequestMapping("/demo")
public class DemoController {
    @Resource
    private DemoService demoService;
    @RequestMapping("/list")
    public String list(Model model) {
        List<Demo> list = demoService.findAllDemo();
        model.addAttribute("list", list);

        return "demo";
    }
}

DemoService.java

@Service
public class DemoService {
    @Resource
    private DemoMapper demoMapper;
    public List<Demo> findAllDemo(){
        return demoMapper.findAllDemo();
    }
}

DemoMapper.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="com.demo.dao.DemoMapper">
    <select id="findAllDemo" resultType="com.demo.pojo.Demo">
        select uuid, user_name username,gender from t_demo
    </select>
</mapper>

DemoMapper.java

public interface DemoMapper {
    public List<Demo> findAllDemo();
}

Demo.java

public class Demo {
    private String uuid;
    private String username;
    private String gender;
    public String getUuid() {
        return uuid;
    }
    public void setUuid(String uuid) {
        this.uuid = uuid;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getGender() {
        return gender;
    }
    public void setGender(String gender) {
        this.gender = gender;
    }
    @Override
    public String toString() {
        return "Demo [uuid=" + uuid + ", username=" + username + ", gender=" + gender + "]";
    }
}
第五步:將專案部署到tomcat下並啟動
專案原始碼
