SPRING IN ACTION 第4版笔记-第五章BUILDING SPRING WEB APPLICATIONS-005-以path parameters的形式给action传参数(value=“{}”、@PathVariable)
一
1.以path parameters的形式给action传参数
@Test
public void testSpittle() throws Exception {
Spittle expectedSpittle = new Spittle("Hello", new Date());
SpittleRepository mockRepository = mock(SpittleRepository.class);
when(mockRepository.findOne(12345)).thenReturn(expectedSpittle); SpittleController controller = new SpittleController(mockRepository);
MockMvc mockMvc = standaloneSetup(controller).build(); mockMvc.perform(get("/spittles/12345"))
.andExpect(view().name("spittle"))
.andExpect(model().attributeExists("spittle"))
.andExpect(model().attribute("spittle", expectedSpittle));
}
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
@RequestMapping(value="/{spittleId}", method=RequestMethod.GET)
public String spittle(
@PathVariable long spittleId,
Model model) {
//The model key will be spittle
model.addAttribute(spittleRepository.findOne(spittleId));
return "spittle";
}
3.view
