二、properties配置与使用

1、默认配置文件

（1）配置-application.properties

# Spring Boot端口配置
server.port=9088
# spring数据源配置
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.password=qaz123
spring.datasource.username=root
spring.datasource.url=jdbc:mysql://192.168.40.111:3306/visualization?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=true
spring.thymeleaf.prefix=classpath:/templates/

（2）读取

Spring Boot自己会读取，配置数据源、thymeleaf等信息

 

2、自定义配置文件

（1）配置-kettle.properties

# properties  https://blog.csdn.net/weixin_42352733/article/details/121830775
environment=xuelei-www
kettle.repository.type=database
kettle.repository.username=admin
kettle.repository.password=admin

（2）使用-读取单个值-PropertiesController.java

package com.boulderaitech.controller;

import com.boulderaitech.entity.KettleRepositoryBean;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.PropertySource;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@Api("properties测试")
@RestController //Controller和RestController的区别
@PropertySource("classpath:kettle.properties") //默认是application.properties
//可以将PropertySource注解加入entity，也可以加入controller将bean注入
public class PropertiesController {
    @Value("${environment}")
    private String envName;

    @Autowired
    private KettleRepositoryBean kettleRepositoryBean;

    @RequestMapping("/getEnv")
    @ApiOperation("properties方式获取当前的环境")
    public String getEnv() {
        return "hello " + envName;
    }
    @ApiOperation("properties方式获取当前的环境")
    @RequestMapping("/getRepoInfo")
    public String getRepoInfo() {
        return "hello " + kettleRepositoryBean.toString();
    }
}

（3）使用-读取多个值到对象-KettleRepositoryBean.java

package com.boulderaitech.entity;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Data
@Component
@NoArgsConstructor
@AllArgsConstructor
@ConfigurationProperties(prefix = "kettle.repository")
public class KettleRepositoryBean {
    private String typ
