springboot读取自定义properties配置文件方法

以你之姓@ 2022-10-29 01:49 200阅读 0赞

1. 添加pom.xml依赖

<dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId> spring-boot-configuration-processor</artifactId>
          <optional> true </optional>
    </dependency>

2. 在resources下建一个config包(当然包名随意), 在包里建一个remote.properties(老规矩, 文件名随意)

3. 在配置文件中写入测试内容

remote.testname=张三
    remote.testpass=123456

4. 写一个实体类, 属性和配置文件对应

import lombok.Data;
    import org.springframework.boot.context.properties.ConfigurationProperties;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.context.annotation.PropertySource;
    import org.springframework.stereotype.Component;
    
    @Configuration
    @ConfigurationProperties(prefix = "remote", ignoreUnknownFields = false)
    @PropertySource("classpath:config/remote.properties")
    @Data
    @Component
    public class RemoteProperties {
        private String testname;
        private int testpass;
    }

5. 在调用配置文件信息的类中搞事情

@EnableConfigurationProperties(RemoteProperties.class)
    @RestController
    public class PageTestController {
    
        @Autowired
        RemoteProperties remoteProperties;
    
        @RequestMapping("testProperties")
        public String testProperties(){
            String str = remoteProperties.getTestname();
            int i = remoteProperties.getTestpass();
            System.out.println(str);
            System.out.println(i);
            return str+i;
        }
    }
