06. ReturnType, Junit [Spring]

01. Return Type

01-1. Contoller

@RequestMapping("/hr/ajax/employees")

public void getAllEmployees(HttpServletResponse response) {

List<EmployeesVO> allEmployees = indexService.getAllEmployees(); StringBuffer

 

employeesInfo = new StringBuffer(); 

for (EmployeesVO employeesVO : allEmployees) { employeesInfo.append(employeesVO.getLastName() + "<br/>");

 } 

// response.setContentType("text/plain"); 

//대부분 이렇게 쓰지만 현재는 <br/>로 인해 아래것을 사용함

response.setContentType("text/html");

response.setCharacterEncoding("UTF-8");

PrintWriter out = null;

try {

out = response.getWriter();

out.write(employeesInfo.toString());

out.flush();

}

catch (IOException e) {

throw new RuntimeException(e.getMessage(), e);

}

finally {

if ( out != null ) {

out.close();

}

}

}

01-2. Json

porn.xml에 jackson-databind 를 추가

@RequestMapping("/hr/ajax/json/employees")

@ResponseBody

public List<EmployeesVO> getAllEmployeesJSON() {

return indexService.getAllEmployees();

}

02. Junit

- 기능 하나하나의 개별적인 테스트를 하기 위함.

porn.xml에서

org.springframework spring-test 추가하기

프로젝트 마우스 오른쪽버튼 - Properties - Java Build Path - Libraries - Add Libraries - Junit - Junit4 선택 후 Finish

src/test/java에 biz, dao, service 패키지를 생성하고 class를 src/main/java와 똑같이 만든다
