I'm using Spring mvc, and wanna make web app which send some json data to client and client should visualized them using js.
I have some questions:
1-My project have some *.html beside *.jsp file how can I handle both without web.xml. the code that i had written work fine with *.jsp but give "The requested resource is not available." error for mapping html files.
2-As i said My service have to send a list of object in json form to client, when i want to parse the json string on server in *.jsp file with the code like
MyClass data = new Gson().fromJson(MyList.get(0).toString(), listType)
,I face with to many problems, so i decide to do this job in client Side in *.html file, i want to know how should i handle this parsing job when i don't want that client know about the the structure my class? OR plz tell if have to share my class with client, how should i send stucture of it to html file?
3-How should i access to data that i created in restapi.jsp on the UserSideApp.html file?
these are some my files:
AppInitializer.java
public class AppInitializer implements WebApplicationInitializer {
public void onStartup(ServletContext container) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(AppConfig.class);
ctx.setServletContext(container);
ServletRegistration.Dynamic servlet = container.addServlet(
"dispatcher", new DispatcherServlet(ctx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
} }
AppConfig.java
public class AppConfig {
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix("");
return viewResolver;
} }
the part of my AppContoller.java
@Controller
@RequestMapping("/")
public class AppController {
@Autowired
HackDataService service;
@RequestMapping(value = "/restapi", method = RequestMethod.GET)
public String jsonAPI(ModelMap model) {
List<HackData> newList = service.findAllNewData();
ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
String json="";
try {
json = ow.writeValueAsString(newList);
} catch (JsonProcessingException e) {
e.printStackTrace();
}
model.addAttribute("List", json);
String newjson = new Gson().toJson(newList);
model.addAttribute("newList", newjson);
return "newTest.jsp";
}
@RequestMapping(value = "/app", method = RequestMethod.GET)
public String htmlapp() {
return "UserSideApp.html";
} }
and my both .html and .jsp files are in "/WEB-INF/views/"
After spending almost a day on first problem, i find the answer of it, first of all instead of implementing WebApplicationInitializer, I extend AbstractAnnotationConfigDispatcherServletInitializer and for java Configing i extends WebMvcConfigurerAdapter.
Then i create a pages folder in WEB-INF and my codes changes to these:
AppInitializer became like other internet's samples.
AppConfig.java
AppController.java
Creating a "resources" directory in "src/main/webapp"
add bellow cod in AppConfig.java
and for viewResolving use the code like bellow:
but still my two other questions are unsolved, the main problem was first one but if you know sth, about these two plz tell me about them
