#### springbootWorkspace

#### 檢查環境設定

#### cmd
mvn
mvn -help

#### 建立專案 DemoSpringBootWebProject
* 可透過網路建立
* (jre)是預設
* 白色是在用的 灰色是目前沒用到的

### package
* **tw.leonchen**
* controller
* model
* config
* product
* model
* controller
* order
* model
* controller

#### HelloController.java

package tw.leonchen.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {
    @RequestMapping(path="/hello.controller", method = RequestMethod.GET)
	public String processAction() {
		return "hello, Controller";
	}
}

### 如果不能執行

### 實作組態檔

#### application.properties

#Server port
#server.port=8081

#data setup資料設定
name=mary
age=18

#profiles information
profiles.username=alice
profiles.address=USA
profiles.phone=N/A

### Person.java

package tw.leonchen.model;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class Person {
	@Value("${name}")
	private String name;
	
	@Value("${age}")
	private int age;
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	
}

#### PersonController.java

package tw.leonchen.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import tw.leonchen.model.Person;

@RestController
public class PersonController {
	@Autowired
	private Person person;
	
	@GetMapping(path = "/person.controller")
	public Person processAction() {
		return person;
	}
}

#### application.yml

#Server port
server:
   port: 8082

#data setup資料設定
name: mary
age: 20

#profiles information
profiles:
   username: louis
   address: Taiwan
   phone: "0987654321"

#### PersonalProfiles.java

package tw.leonchen.model;


import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "profiles")
public class PersonalProfiles {

	private String username;
	private String address;
	private String phone;
	
	
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}
	public String getPhone() {
		return phone;
	}
	public void setPhone(String phone) {
		this.phone = phone;
	}
	
	
}


#### PersonalProfilesController.java

package tw.leonchen.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import tw.leonchen.model.PersonalProfiles;

@RestController
public class PersonalProfilesController {
	@Autowired
	private PersonalProfiles pp1;
	
	@GetMapping("/personalProfiles.controller")
	public PersonalProfiles processAction() {
		return pp1;
	}
}

## 看優先權

#### PathVaribleController.java

package tw.leonchen.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class PathVaribleController {
	@GetMapping("/member/{mid}")
	@ResponseBody                                                              //true 一定要給值
	public String processPathVariableAction(@PathVariable(name = "mid", required = true )String memberId) {
		return "memberId:" + memberId;
	}
}

#### DemoSpringBootWebProjectApplication
* 加入Servlet

package tw.leonchen;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;

@SpringBootApplication
@ServletComponentScan
public class DemoSpringBootWebProjectApplication {

	public static void main(String[] args) {
		SpringApplication.run(DemoSpringBootWebProjectApplication.class, args);
	}

}

#### MyServletfilter.java

package tw.leonchen.filter;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;

@WebFilter("/")
public class MyServletfilter implements Filter{

	
	@Override
	public void doFilter(ServletRequest request,ServletResponse response,FilterChain chain)throws IOException,ServletException{
		response.setContentType("text/html;charset=UTF=8");
		PrintWriter out = response.getWriter();
		System.out.println("execute filter ready");
		
		chain.doFilter(request, response);
		
		System.out.println("execute filter finished");
		
		out.close();
	}
}
