Spring-集成环境

集成Junit

        
            org.springframework
            spring-test
            5.3.17
        
        
            junit
            junit
            4.13.2
            test
        

package com.sjj.service;

import com.sjj.config.SpringConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
// @ContextConfiguration("classpath:appContext.xml") // Spring配置文件方式
@ContextConfiguration(classes = SpringConfig.class) // 注解配置方式
public class UserServiceTest {
    /**
     * 集成junit测试
     */
    @Autowired  // 注入需要测试的对象
    private UserService userService;
    @Test
    public void test(){
        userService.UserServiceTest(); // 测试UserService的UserServiceTest方法
    }
}

集成Web环境

先添加依赖

        
            org.springframework
            spring-web
            5.3.17
        
        
            javax.servlet
            javax.servlet-api
            3.1.0
        
        
            javax.servlet.jsp
            javax.servlet.jsp-api
            2.3.3
        

    
        study_Spring03
        
          
            
              maven-clean-plugin
              3.1.0
            
            
            
              maven-resources-plugin
              3.0.2
            
            
              maven-compiler-plugin
              3.8.0
            
            
              maven-surefire-plugin
              2.22.1
            
            
              maven-war-plugin
              3.2.2
            
            
              maven-install-plugin
              2.5.2
            
            
              maven-deploy-plugin
              2.8.2
            
          
        
      

编写一个servlet类

package com.sjj.web;

import com.sjj.config.SpringConfig;
import com.sjj.service.UserService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.stereotype.Controller;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Controller("userServlet")
public class UserServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        ApplicationContext app = new AnnotationConfigApplicationContext(SpringConfig.class);
        UserService userService = (UserService) app.getBean("userService");
        userService.userServiceTest();
    }
}

准备好webapp内容

将项目部署到tomcat
