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
