  • SpringBoot项目中,获取配置文件信息

    1.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

    2.获取配置文件信息(三种方法)

    2.1@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;
    }

    2.2@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;
    }

    单元测试结果

    2.3org.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);
        }
    }
