Spring Boot Controller (2) Thymeleaf 複雜例子
===

[TOC]

## 目的

有一個java的數據結構在後端產生了，可能是List或是HashMap要如何將它放進thymeleaf裡面

## key


## MailHTMLContentBuilder

import java.util.Map;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;

@Service
public class MailHTMLContentBuilder {
	
	Logger LOG = LoggerFactory.getLogger(MailHTMLContentBuilder.class);
	
	private TemplateEngine templateEngine;
	
	@Autowired
    public MailHTMLContentBuilder(TemplateEngine templateEngine) {
        this.templateEngine = templateEngine;
    }

    public String generateMailContent(String templateFilePath, Map<String, Object> templateModelValueMap) {
        Context context = new Context();
        context.setVariables(templateModelValueMap);
        
        return templateEngine.process(templateFilePath, context);
    }

}

## 傳送email附檔案是htmltable的信件

@Service
public class DemoThymeleafTable_SERVICE {
	
	private static Logger logger = LoggerFactory.getLogger(DemoThymeleafTable_SERVICE.class);
	
	@Autowired
	EmailService emailService;
	
	@Autowired
	MailHTMLContentBuilder mailHTMLContentBuilder; // help us use thylmeleaf
	
	public void sayHI() {
		
		logger.info("HI");
		System.out.println("HI");
	}
	
	public List <JoinAI_RatioBean> giveMeJoinAI_RatioBeanListData( ) {
		
		List <JoinAI_RatioBean> myList = new ArrayList<JoinAI_RatioBean>() ;
		
		JoinAI_RatioBean data1= new JoinAI_RatioBean("A","AP1583","mike",0,0, null );
		JoinAI_RatioBean data2= new JoinAI_RatioBean("A","AP1582","sandy",85,90, null );
		JoinAI_RatioBean data3= new JoinAI_RatioBean("B","AP1587","mike",52,25, null );
		JoinAI_RatioBean data4= new JoinAI_RatioBean("B","AP1587","Robin",52,25, null );
		JoinAI_RatioBean data5= new JoinAI_RatioBean("B","AP1587","ELmo",52,25, null );
		myList.add(data1);
		myList.add(data2);
		myList.add(data3);
		myList.add(data4);
		myList.add(data5);

		return myList;
	}
	
	
	public void demoThymeleafTemplateWithTable() {
		
		String[] toPrimaryString =new String[] {"[e-mail]","[e-mail]"};
		String[] toCcStrings =null;
		String subjectString ="Demo Sending HTML";
		
		String templateFilePathString="DemoThymeleafTemplateWithTableControl.html";
		
		//Data 
		List <JoinAI_RatioBean> myDataList = giveMeJoinAI_RatioBeanListData( );
		
		for (JoinAI_RatioBean each: myDataList) {
			logger.info(each.toString());
		}
		
		// Thymeleaf model
		Map<String, Object> templateModelValueMap=new HashMap<>();
		
		templateModelValueMap.put("title", "d");
		templateModelValueMap.put("mydataList", myDataList);
		
		String mailHTMLBodyString=mailHTMLContentBuilder.generateMailContent(templateFilePathString, templateModelValueMap);
		emailService.sendHTMLMail(subjectString,mailHTMLBodyString,toPrimaryString);
		
		
	}
	
	public void demoThymeleafTemplateWithTable2() {
		
		String[] toPrimaryString =new String[] {"[e-mail]","[e-mail]"};
		String[] toCcStrings =null;
