如何通过定义JavaBena同时自定义多个自定义属性？

跟杨春娟学SpringBoot笔记：如何通过定义JavaBena同时自定义多个自定义属性？

完成：第一遍

1.如何通过定义JavaBena同时自定义多个自定义属性？

步骤一:创建AWSConfigBean.java

AWSConfigBean.java

Bean上@ConfigurationProperties(prefix=“myboot.aws”)

package com.springboot.demo.SpringBootDemoProject.configuration;

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

@ConfigurationProperties(prefix="myboot.aws")
public class AWSConfigBean {
	private String key;
	private String region;
	private String bucketName;
	private String show;
	public String getKey() {
		return key;
	}
	public void setKey(String key) {
		this.key = key;
	}
	public String getRegion() {
		return region;
	}
	public void setRegion(String region) {
		this.region = region;
	}
	public String getBucketName() {
		return bucketName;
	}
	public void setBucketName(String bucketName) {
		this.bucketName = bucketName;
	}
	public String getShow() {
		return show;
	}
	public void setShow(String show) {
		this.show = show;
	}
	
	
}

步骤二：新建RandomConfigBean.java

RandomConfigBean.java

package com.springboot.demo.SpringBootDemoProject.configuration;

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

@ConfigurationProperties(prefix="myboot.random")
public class RandomConfigBean {
	private String secret;
	private int number;
	private long bigNumber;
	private String uuid;
	private int ten;
	private int range;
	public String getSecret() {
		return secret;
	}
	public void setSecret(String secret) {
		this.secret = secret;
	}
	public int getNumber() {
		return number;
	}
	public void setNumber(int number) {
		this.number = number;
	}
	public long getBigNumber() {
		return bigNumber;
	}
	public void setBigNumber(long bigNumber) {
		this.bigNumber = bigNumber;
	}
	public String getUuid() {
		return uuid;
	}
	public void setUuid(String uuid) {
		this.uuid = uuid;
	}
	public int getTen() {
		return ten;
	}
	public void setTen(int ten) {
		this.ten = ten;
	}
	public int getRange() {
		return range;
	}
	public void setRange(int range) {
		this.range = range;
	}
}

步骤三：修改ConfigurationPageController利用 @Autowired 添加AWSConfigBean 和RandomConfigBean

package com.springboot.demo.SpringBootDemoProject.configuration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("c")
public class ConfigurationPageController {

	@Value("${myboot.aws.key}")
	private String awsKey;
	
	@Value("${myboot.aws.region}")
	private String awsRegion;
	
	@Value("${myboot.aws.bucketName}")
	private String awsBucketName;
	
	@Autowired
	private AWSConfigBean aWSConfigBean;
	
	@Autowired
	private RandomConfigBean randomConfigBean;
	
	@RequestMapping("value")
	public String show(ModelMap model) {
		model.addAttribute("awsKey", awsKey);
		model.addAttribute("awsRegion", awsRegion);
		model.addAttribute("awsBucketName", awsBucketName);
		model.addAttribute("configBean", aWSConfigBean);
		model.addAttribute("randomConfigBean", randomConfigBean);
		return "config";
	}
}

步骤四：在启动类中添加@EnableConfigurationProperties({AWSConfigBean.class, RandomConfigBean.class})

SpringBootDemoProjectApplication

package com.springboot.demo.SpringBootDemoProject;

import org.springframework.boot.Banner.Mode;
import org.springframework.boot.ResourceBanner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.io.ClassPathResource;

import com.springboot.demo.SpringBootDemoProject.configuration.AWSConfigBean;
import com.springboot.demo.SpringBootDemoProject.configuration.RandomConfigBean;

@SpringBootApplication
@PropertySource("classpath:config.properties")
@EnableConfigurationProperties({AWSConfigBean.class, RandomConfigBean.class})
public class SpringBootDemoProjectApplication {

	public static void main(String[] args) {
		SpringApplication.run(SpringBootDemoProjectApplication.class, args);	
		SpringApplication springApplication = new SpringApplication(SpringBootDemoProjectApplication.class);
		
		
	}

}

步骤五：修改config.html

config.html

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
	<title>This is a Configuration Test page</title>
	<meta http-equiv="Content-Type" content="text/html;charset=UTF-8"/>
</head>
<body>
	This is Configuration Test page!
	
	<p th:text="${configBean.key}"></p>
	<p th:text="${configBean.region}"></p>
	<p th:text="${configBean.bucketName}"></p>
	<p th:text="${'this is show'+configBean.show}"></p>
	
	<p>Following is random value</p>
	<p th:text="${'secret:'+randomConfigBean.secret}"></p>
	<p th:text="${'number:'+randomConfigBean.number}"></p>
	<p th:text="${'bigNumber:'+randomConfigBean.bigNumber}"></p>
	<p th:text="${'uuid:'+randomConfigBean.uuid}"></p>
	<p th:text="${'ten'+randomConfigBean.ten}"></p>
	<p th:text="${'range'+randomConfigBean.range}"></p>
</body>
</html>
