一
1.以path parameters的形式给action传参数
1 @Test 2 public void testSpittle() throws Exception { 3 Spittle expectedSpittle = new Spittle("Hello", new Date()); 4 SpittleRepository mockRepository = mock(SpittleRepository.class); 5 when(mockRepository.findOne(12345)).thenReturn(expectedSpittle); 6 7 SpittleController controller = new SpittleController(mockRepository); 8 MockMvc mockMvc = standaloneSetup(controller).build(); 9 10 mockMvc.perform(get("/spittles/12345")) 11 .andExpect(view().name("spittle")) 12 .andExpect(model().attributeExists("spittle")) 13 .andExpect(model().attribute("spittle", expectedSpittle)); 14 }
在浏览器中访问：http://localhost:8080/SpringInAction4_Chapter5_SpringMVC01/spittles/1
2.controller
package spittr.web; import java.util.Date; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import spittr.Spittle; import spittr.data.SpittleRepository; @Controller @RequestMapping("/spittles") public class SpittleController { private static final String MAX_LONG_AS_STRING = "9223372036854775807"; private SpittleRepository spittleRepository; @Autowired public SpittleController(SpittleRepository spittleRepository) { this.spittleRepository = spittleRepository; } @RequestMapping(value="/{spittleId}", method=RequestMethod.GET) public String spittle( @PathVariable("spittleId") long spittleId, Model model) { //The model key will be spittle model.addAttribute(spittleRepository.findOne(spittleId)); return "spittle"; } }
在保证spittleId名称一致的情况下，可以简写
1 @RequestMapping(value="/{spittleId}", method=RequestMethod.GET) 2 public String spittle( 3 @PathVariable long spittleId, 4 Model model) { 5 //The model key will be spittle 6 model.addAttribute(spittleRepository.findOne(spittleId)); 7 return "spittle"; 8 }
3.view
1 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> 2 <html> 3 <head> 4 <title>Spitter</title> 5 <link rel="stylesheet" 6 type="text/css" 7 href="<c:url value="/resources/style.css" />" > 8 </head> 9 <body> 10 <div class="spittleView"> 11 <div class="spittleMessage"><c:out value="${spittle.message}" /></div> 12 <div> 13 <span class="spittleTime"><c:out value="${spittle.time}" /></span> 14 </div> 15 </div> 16 </body> 17 </html>
