二、properties配置與使用
1、預設配置文件
(1)配置-application.properties
# Spring Boot埠配置
server.port=9088
# spring數據源配置
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)讀取
Spring Boot自己會讀取,配置數據源、thymeleaf等信息
2、自定義配置文件
(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-讀取單個值-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測試")
@RestController //Controller和RestController的區別
@PropertySource("classpath:kettle.properties") //預設是application.properties
//可以將PropertySource註解加入entity,也可以加入controller將bean註入
public class PropertiesController {
@Value("${environment}")
private String envName;
@Autowired
private KettleRepositoryBean kettleRepositoryBean;
@RequestMapping("/getEnv")
@ApiOperation("properties方式獲取當前的環境")
public String getEnv() {
return "hello " + envName;
}
@ApiOperation("properties方式獲取當前的環境")
@RequestMapping("/getRepoInfo")
public String getRepoInfo() {
return "hello " + kettleRepositoryBean.toString();
}
}
(3)使用-讀取多個值到對象-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 type;
private String username;
private String password;
}
三、yml配置
1、預設配置文件
application.yml
2、自定義配置文件
(1)配置-repository.yml
kettle:
repository:
repo1:
type: postgresql
ip_addr: 192.168.4.68
port: 5432
username: admin
password: admin
db_name: kettle
version: 8.0.0
(2)實現任意位置讀取的工廠類-YamlConfigFactory.java
package com.boulderaitech.factory;
import org.springframework.beans.factory.config.YamlPropertiesFactoryBean;
import org.springframework.core.env.PropertiesPropertySource;
import org.springframework.core.env.PropertySource;
import org.springframework.core.io.support.DefaultPropertySourceFactory;
import org.springframework.core.io.support.EncodedResource;
import java.io.IOException;
import java.util.Properties;
/**
* 在任意位置讀取指定的yml文件
* 參考:https://blog.csdn.net/weixin_45168162/article/details/125427465
*/
public class YamlConfigFactory extends DefaultPropertySourceFactory {
//繼承父類,可以重載父類方法@Override
//實現介面,重寫方法@Override
@Override
public PropertySource<?> createPropertySource(String name, EncodedResource resource) throws IOException {
String sourceName = name != null ? name : resource.getResource().getFilename();
if (!resource.getResource().exists()) {
return new PropertiesPropertySource(sourceName, new Properties());
} else if (sourceName.endsWith(".yml") || sourceName.endsWith(".yaml")) {
Properties propertiesFromYaml = loadYml(resource);
return new PropertiesPropertySource(sourceName, propertiesFromYaml);
} else {
return super.createPropertySource(name, resource);
}
}
private Properties loadYml(EncodedResource resource) throws IOException {
YamlPropertiesFactoryBean factory = new YamlPropertiesFactoryBean();
factory.setResources(resource.getResource());
factory.afterPropertiesSet();
return factory.getObject();
}
}
(3)使用-讀取單個值-KettleEnvBean.java
package com.boulderaitech.entity;
import com.boulderaitech.factory.YamlConfigFactory;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
@Data
@Component
@AllArgsConstructor
@NoArgsConstructor
@PropertySource(value = "classpath:repository.yml",factory = YamlConfigFactory.class)//需要通過工廠載入指定的配置文件
public class KettleEnvBean {
@Value("${kettle.version}")
private String kettleVersion;
}
(4)使用-讀取多個值到對象-KettleRepositoryYmlBean.java
package com.boulderaitech.entity;
import com.boulderaitech.factory.YamlConfigFactory;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
@Data
@AllArgsConstructor
@NoArgsConstructor
@PropertySource(value = "classpath:repository.yml",factory = YamlConfigFactory.class)//需要通過工廠載入指定的配置文件
@ConfigurationProperties(prefix = "kettle.repository.repo1") //需要添加spring boot的註解,才可以使用
//思考:能否通過反射操作修改註解的參數
@Component()
public class KettleRepositoryYmlBean {
private String type;
private String ip_addr; //命名只能用下劃線
private String username;
private String password;
private String port;
private String db_name;
}
(5)使用-YmlController.java
package com.boulderaitech.controller;
import com.boulderaitech.entity.KettleEnvBean;
import com.boulderaitech.entity.KettleRepositoryYmlBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController //使用controller返回的結果會按照template進行解析
//使用RestController則會返回對應的字元串
public class YmlController {
@Autowired
private KettleRepositoryYmlBean kettleRepositoryYmlBean;
@Autowired
private KettleEnvBean kettleEnvBean;
@RequestMapping(value = "/getKettleVersion") //預設是get
public String getKettleVersion() {
return "hello " + kettleEnvBean.getKettleVersion();
}
// @GetMapping("/getRepoInfoYml"),不支持get方法
//@RequestMapping(value = "/getRepoInfoYml", method = RequestMethod.POST)
@RequestMapping(value = "/getRepoInfoYml")
public String getRepoInfoYml() {
return "hello " + kettleRepositoryYmlBean.toString();
}
}
