SpringBoot--读取自定义配置文件

新建配置文件 custom-config.yaml

my-app:
  auth-filter:
    secretKey: mySecretKey
    expirationTime: 864000000 # 10 天
    excludes:
      - /shore/demo/user/login
      - /shore/demo/user/register
      - /shore/demo/user/query

application.yaml 配置新文件路径

spring:
  config:
    import: classpath:custom-config.yaml

新建配置类映射配置属性

package com.shore.my_spring_demo.web.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

import java.util.List;

@Component
@ConfigurationProperties(prefix = "my-app.auth-filter")
@Data
public class CustomConfig {
    private String secretKey;
    private long expirationTime;

    private List<String> excludes;
}

启动类配置 CustomConfig

可选，高版本SpringBoot 已经可以自动注入 @Compont 注解的类

package com.shore.my_spring_demo;

import com.shore.my_spring_demo.web.config.CustomConfig;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;

@SpringBootApplication
@EnableConfigurationProperties(CustomConfig.class)
public class MySpringDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(MySpringDemoApplication.class, args);
    }

}

使用

通过 @Resource 注解注入，然后就可以使用了

package com.shore.my_spring_demo.service.jwt;

import com.shore.my_spring_demo.common.enums.ErrorEnums;
import com.shore.my_spring_demo.exception.UsersException;
import com.shore.my_spring_demo.web.config.CustomConfig;
import com.shore.my_spring_demo.web.config.JwtConfig;
import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.security.KeyPair;
import java.util.Date;

@Slf4j
@Service
public class JwtServiceImpl implements JwtService {
    @Resource
    private CustomConfig customConfig;

    @Resource
    private KeyPair keyPair;

                .claim("sub", username)
                .expiration(new Date(System.currentTimeMillis() + customConfig.getExpirationTime()))
                .signWith(SignatureAlgorithm.RS256, keyPair.getPrivate())
                .compact();
    }
}
