最近有空所以把以前做項目的框架做個簡單的整合
1.創建Maven項目，導入依賴
junit junit 4.12 test javax.servlet javax.servlet-api 4.0.0 provided javax.servlet jstl 1.2 mysql mysql-connector-java 5.1.38 com.mchange c3p0 0.9.5.2 org.springframework spring-webmvc 5.0.8.RELEASE org.springframework spring-jdbc 5.0.8.RELEASE org.mybatis mybatis 3.4.6 org.mybatis mybatis-spring 1.3.2 redis.clients jedis 2.9.0 com.alibaba fastjson 1.2.7 ssm_redis src/main/java **/*.xml maven-clean-plugin 3.0.0 maven-resources-plugin 3.0.2 maven-compiler-plugin 3.7.0 maven-surefire-plugin 2.20.1 maven-war-plugin 3.2.0 maven-install-plugin 2.5.2 maven-deploy-plugin 2.8.2
2.根據個人習慣創建包
3.在resources中創建db.properties
db.driver=com.mysql.jdbc.Driver db.url=jdbc:mysql://127.0.0.1:3306/Bloggingplatform?characterEncoding=utf-8&allowMultiQueries=true db.user=root db.password=@838061522@ly #定義初始連接數 initPoolSize=3 #定義最大連接數 maxPoolSizes=30
4.在resources中創建spring.xml
5.在pojo中創建實體類
public class Article implements Serializable{
private static final long serialVersionUID = 1L;
private String aId; //文章id
private String aTitle; //標題
private String aContent; //內容
private String aTitleImg; //標題圖片
private String aTime; //時間
private Integer aReadingQuantity; //閱讀量
private Integer aCommentnum; //評論數
private Programa programa;//欄目id 外鍵
private String label;//標籤
private Administrator administrator;//管理員id 外鍵
private Integer aStatusBar; //狀態 0不公開 1公開
private String aAbstract;//摘要
//此處省略setter和getter
}
6.創建dao接口 ArticleDao
public interface ArticleDao {
/*
* @Author Uncle Liu
* @Description //TODO 根據id查詢Article
* @Date 18:36 2018/10/30
**/
Article getArticleById(String aId);
}
7.創建service接口及實現類
7.1 創建ArticleService
public interface ArticleService {
/*
* @Author Uncle Liu
* @Description //TODO 根據id查詢Article
* @Date 18:36 2018/10/30
**/
Article getArticleById(String aId);
}
7.2 創建ArticleImpl
@Service("articleImpl")
public class ArticleImpl implements ArticleService {
@Override
public Article getArticleById(String aId) {
return articleDao.getArticleById(aId);
}
}
8.在mappers中創建ArticleMapper.xml
9.配置web.xml
Archetype Created Web Application index.jsp contextConfigLocation classpath:spring.xml encodingFilter org.springframework.web.filter.CharacterEncodingFilter encoding UTF-8 encodingFilter /* SpringMVC org.springframework.web.servlet.DispatcherServlet contextConfigLocation classpath:spring.xml 1 SpringMVC *.do org.springframework.web.context.ContextLoaderListener
10.創建Controller
@Controller
@RequestMapping("/index")
public class indexController {
@Resource
private ArticleService articleService;
@RequestMapping("/a")
@ResponseBody
public String index(){
//根據id查詢
Article article = articleService.getArticleById("91cf33d3-2b96-45e8-a66d-ffd7fabb8de8");
System.out.println(article);
return "Hello";
}
}
11.創建index.jsp
