SpringBoot 项目中,获取配置文件信息
在配置文件中设置信息,格式如下
wechat:
mpAppId: wxdf2b09f280e6e6e2
mpAppSecret: f924b2e9f140ac98f9cb5317a8951c71
如果是多级目录,则
project:
url:
sell: http://localhost:8080
获取配置文件信息(三种方法)
1、@ConfigurationProperties
package com.xiong.sell.config;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Data
@Component
@ConfigurationProperties(prefix = "wechat")
public class WechatAccountConfig {
private String mpAppId;
private String mpAppSecret;
}
2、@Value
package com.xiong.sell.config;
import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Component
@Data
//@ConfigurationProperties(prefix = "project.url")
public class ProjectUrlConfig {
@Value("${project.url.sell}")
private String sell;
}
3、org.springframework.core.env.Environment
package com.xiong.sell.config;
import lombok.extern.slf4j.Slf4j;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.core.env.Environment;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@Slf4j
public class ConfigTest {
@Autowired
private Environment environment;
@Test
public void test2(){
String sell = environment.getProperty("project.url.sell");
log.info("project.url.sell = {}",sell);
}
}
