实验报告4-实现分页功能
一、实现思路
打包运行商品分页项目。要求：
1、测试项目service层的分页功能，
2、controller层添加first()并测试
3、将项目打为JAR包并运行，
4、将项目打为WAR包并运行。
二、实验步骤
1、测试项目service层的分页功能
service层，GoodsService.java，paging()添加测试
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.NONE)
class GoodsServiceTest {@Autowiredprivate GoodsService goodsService;@Testvoid paging() {Integer page = 0;Integer size = 6;Page<Goods> paging = goodsService.paging(page, size);long totalElements = paging.getTotalElements();int totalPages = paging.getTotalPages();List<Goods> goodsList = paging.getContent();System.out.println("totalElements="+totalElements);System.out.println("totalPages="+totalPages);for (Goods goods : goodsList) {System.out.println(goods);}}
}2、测试项目service层的分页功能
controller层，GoodsController.java，first()
@ResponseBody@RequestMapping("/first")public String first(){System.out.println("first method is running");return "Welcome to Spring Boot Application";}controller层，GoodsController.java，测试first()
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureMockMvc
class GoodsControllerTest {@Testvoid page(@Autowired MockMvc mvc) throws Exception {//创建虚拟请求MockHttpServletRequestBuilder builder= MockMvcRequestBuilders.get("/goods/first");//执行请求mvc.perform(builder);}
}3、打为jar包
添加maven打包插件
<build><finalName>${project.artifactId}</finalName><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build>打包。Maven→项目名→Lifecycle→clean→package
运行。java -jar PageBySpringBoot.jar
4、打为war包
设置项目路径
server:servlet:context-path: /goodsPage解决静态资源访问失效问题，修改为thymeleaf的th属性动态访问
设置打包方式为war
<version>1.0-SNAPSHOT</version><packaging>war</packaging>排除内置Tomcat
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><exclusions><exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId></exclusion></exclusions></dependency>添加Tomcat依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId><!--仅在编译和测试阶段使用--><scope>provided</scope></dependency>添加maven打包插件
<build><finalName>${project.artifactId}</finalName><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build>修改启动类
@SpringBootApplication
@ServletComponentScan
public class PageBySpringBootApplication extends SpringBootServletInitializer {public static void main(String[] args) {SpringApplication.run(PageBySpringBootApplication.class,args);}@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {return builder.sources(PageBySpringBootApplication.class);}
}打包。Maven→项目名→Lifecycle→clean→package
tomcat运行war tomcat\bin目录，startup.bat
