java中如何搭建ssj框架的項(xiàng)目

發(fā)布時(shí)間:2020-07-22 11:04:27 來(lái)源:億速云 閱讀:168 作者:小豬 欄目:編程語(yǔ)言

這篇文章主要講解了java中如何搭建ssj框架的項(xiàng)目,內(nèi)容清晰明了,對(duì)此有興趣的小伙伴可以學(xué)習(xí)一下,相信大家閱讀完之后會(huì)有幫助。

1.新建一個(gè)maven項(xiàng)目

2.在pom.xml中,配置所需的jar包及其版本號(hào)

  <!-- 設(shè)置自定義屬性和值 -->

  <spring.version>4.1.7.RELEASE</spring.version>
  <hibernate.version>4.3.11.Final</hibernate.version>

3.建造完成后,自動(dòng)生成一個(gè)web.xml

在web.xml中:
 A. 加載Spring配置文件
 B. 配置Spring的監(jiān)聽(tīng)
 C. 配置SpringMVC的核心控制器
 D. 配置編碼過(guò)濾器,作用:防止中文亂碼
 E. 配置驗(yàn)證碼相關(guān)servlet(有需要的話)

代碼如下:

<!-- 加載Spring配置文件 -->
 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:applicationContext.xml</param-value>
 </context-param>
 
 <!--配置Spring的監(jiān)聽(tīng)-->
 <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>
  
 <!-- 配置SpringMVC的核心控制器 攔截所有請(qǐng)求 -->
 <servlet>
  <servlet-name>springMVC</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:springMVC.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
 </servlet>
 <servlet-mapping>
  <servlet-name>springMVC</servlet-name>
  <url-pattern>/</url-pattern>
 </servlet-mapping> 
 
 <!-- 配置編碼過(guò)濾器,作用:防止中文亂碼 -->
 <filter>
  <filter-name>abc</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  <async-supported>true</async-supported>
  <init-param>
  <param-name>encoding</param-name>
  <param-value>utf-8</param-value>
  </init-param>
 </filter>
 <filter-mapping>
  <filter-name>abc</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>
 
 <!-- 配置驗(yàn)證碼相關(guān)servlet -->
<servlet>
 <servlet-name>CheckCodeServlet</servlet-name>
 <servlet-class>cn.fh.servlet.CheckCodeServlet</servlet-class>
 </servlet> 
 
 <servlet-mapping>
 <servlet-name>CheckCodeServlet</servlet-name>
 <url-pattern>/CheckCodeServlet</url-pattern>
 </servlet-mapping> 

4.在resources文件夾下,創(chuàng)建并配置applicationContext.xml和springMVC.xml文件

applicationContext.xml中詳細(xì)配置:
A. 創(chuàng)建數(shù)據(jù)源:創(chuàng)建c3p0連接池,連接數(shù)據(jù)庫(kù)
B. 根據(jù)數(shù)據(jù)源,創(chuàng)建實(shí)體管理工廠
C. 配置事務(wù)
D. SpringDataJpa的相關(guān)配置 
E. 開(kāi)啟組件的掃描
F. 定義advice,配置傳播特性、事務(wù)隔離級(jí)別、只讀事務(wù)、回滾策略
G. 切點(diǎn)配置 execution   

springMVC.xml
A. 開(kāi)啟注解
B. 放開(kāi)靜態(tài)資源
C. 配置視圖解析器
D. 上傳文件相關(guān)配置
E. 注冊(cè)攔截器

5.新建model層,在實(shí)體類中,通過(guò)注解的方式來(lái)配置數(shù)據(jù)庫(kù)中表的信息

@Entity 表明這是一個(gè)實(shí)體類
@Table(name = "")在數(shù)據(jù)庫(kù)中生成對(duì)應(yīng)的表名
@Id聲明主鍵
@GeneratedValue設(shè)置主鍵生成策略
 GenerationType.IDENTITY  mySql主鍵生成策略
 GenerationType.SEQUENCE  oracle主鍵生成策略
 GenerationType.AUTO  根據(jù)不同的數(shù)據(jù)庫(kù),設(shè)置對(duì)應(yīng)的主鍵生成策略

6.新建repository層,并創(chuàng)建接口,同時(shí)繼承兩個(gè)接口

其中:

 分別是: JpaRepository<T,ID>和JpaSpecificationExecutor<T>
  T 與model層對(duì)象相對(duì)應(yīng)
  ID跟model層對(duì)象Id的類型相對(duì)應(yīng)
  JpaRepository:排序,分頁(yè),一些簡(jiǎn)單的增刪改查
  JpaSpecificationExecutor:復(fù)雜的動(dòng)態(tài)條件查詢

7.新建service serviceImpl controller層,并完成自動(dòng)注入(通過(guò)@Autowired注解)

其中:

serviceImpl類中注入repository

@Autowired
private UserRepository userRepository;

controller層中注入service

@Autowired
private UserService userService;

8.新建controller層之后,先測(cè)試一下項(xiàng)目的視圖解析器(@RequestMapping) 和springMVC攔截器(主要通過(guò)@ResponseBody注解,把返回的結(jié)果轉(zhuǎn)換為json格式,給瀏覽器),然后再進(jìn)行后續(xù)代碼的具體編寫。

// 測(cè)試攔截器
@RequestMapping("test") 
@ResponseBody
public String test(){
 return "test";
}

// 測(cè)試SpringMVC視圖解析器
@RequestMapping("toIndex")
public String toIndex(){
 return "index";
}

9.將項(xiàng)目部署到tomcat下,并運(yùn)行此項(xiàng)目。

看完上述內(nèi)容,是不是對(duì)java中如何搭建ssj框架的項(xiàng)目有進(jìn)一步的了解,如果還想學(xué)習(xí)更多內(nèi)容,歡迎關(guān)注億速云行業(yè)資訊頻道。
