<Spring Boot>
1, 스프링 부트 설치하기
artifact : 제목
Packaging : War로 하면 tomcat 밑에 배포하는 것임. Jar로 하면 tomcat 없이 배포하는 것임. 서버를 내장시켜줌.
Java : 자바 버전을 선택함. 지금까지는 자바 11버전으로 함.
상단 선택 후 generate.
하지만 spring 프로그램 내에서도 상단과 똑같은 과정으로 설치할 수 있다.

Spring Web을 선택해야 MVC 관련한 모델들이 다운된다.
(중요 : 면접에서 물어볼 수 있음.) 스프링 버전 2.7.5 사용함, 가장 최신 버전 사용.
java > com.oracle.oBootHello(package) > new package > controller 생성
상단과 같은 방법으로
service (package)
repository (package)
domain (package)
생성
spring boot에서는 pom.xml 역할을 하는 것이 build.gradle이다.
resources > application.properties
server.port=8381
controller > HelloController (class)
Logger와 LoggerFactory 자동완성 시 org.slf4j 선택하기.
package com.oracle.oBootHello.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.oracle.oBootHello.domain.Emp;
@Controller
public class HelloController {
private static final Logger logger = LoggerFactory.getLogger(HelloController.class);
/* 경로가 자동으로 templates로 돼있음. */
// Prefix -> templates
// suffix -> .html
@RequestMapping("hello")
public String hello(Model model) {
logger.info("start...");
model.addAttribute("parameter", "boot start...");
return "hello";
}
/* @ResponseBody : 페이지를 이동하지 않고 나를 호출한 html 몸통에 반환한다. */
@ResponseBody
@GetMapping("ajaxString")
/* @RequestParam는 필수값을 가져가야 함.
* url에 /ajaxString?ajaxName=값 와 같은 식으로 ajaxName의 값을 넘겨주어야 함. */
public String ajaxString(@RequestParam("ajaxName") String aName) {
System.out.println("HelloController ajaxString aName->" + aName);
return aName;
}
@ResponseBody
@GetMapping("ajaxEmp") /* ajax로 돌아간다. */
/* url에 /ajaxEmp?empno=값&ename=값으로 두 개의 파라미터를 받음 */
public Emp ajaxEmp(@RequestParam("empno") String empno, @RequestParam("ename") String ename) {
System.out.println("HelloController ajaxEmp empno->" + empno);
logger.info("ename-> {}", ename);
Emp emp = new Emp();
/* setter를 이용해서 값을 넣음. */
emp.setEmpno(empno);
emp.setEname(ename);
return emp;
}
}spring boot에서는 prefix가 templates이고 suffix가 html이다.
그래서 코드 작성을 src/main/java와 src/main/resources에만 작성한다.
(이전에는 prefix는/WEB-INF/views/, suffix는 jsp였다. 그래서 코드 작성을 src 폴더에 작성했었다.)
resources > templates > hello.html (html)
<!DOCTYPE html>
<html xml:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>hello.html</h1>
<!-- thymeleaf 쓸 때의 문법 -->
<p th:text="안녕+ ${parameter}">
</body>
</html>실행 방법 : 프로젝트 우클릭 > Run As > Spring Boot App
resources > static/index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>나 Index야</h1>
<!-- 화면의 hello를 선택하면 /hello 페이지로 이동한다. -->
<a href="/hello">Hello</a>
</body>
</html>
다시 실행할 때는 이 Relaunch 버튼 누름
사용하고 있는 포트(8381)에 relaunch를 한다는 뜻이다.
Tomcat initialized with port(s): 8381 (http)
Tomcat started on port(s): 8381 (http) with context path ''
으로 실행되고 있기 때문이다.
index.html을 Relaunch 후 url에 http://localhost:8381 를 친다
Hello를 누르면 하단과 같이 페이지가 이동된다. 이렇게 페이지를 연결할 수 있다.
java > domain(package) < Emp.java(class)
객체를 던져주기 위해 객체 생성
package com.oracle.oBootHello.domain;
public class Emp {
private String empno;
private String ename;
public String getEmpno() {
return empno;
}
public void setEmpno(String empno) {
this.empno = empno;
}
public String getEname() {
return ename;
}
public void setEname(String ename) {
this.ename = ename;
}
}
