spring boot 添加自定义属性

1.添加jar

compile('org.springframework.boot:spring-boot-configuration-processor:1.2.0.RELEASE')

2.在application.properties中设置自定义属性

#------微信App支付参数------
#终端设备号(门店号或收银设备ID)，默认请传"WEB"
weixinpay.device_info=WEB
#符合ISO 4217标准的三位字母代码，默认人民币：CNY，其他值列表详见货币类型
weixinpay.fee_type=CNY
#微信开放平台审核通过的应用APPID
weixinpay.appid=*******
#微信支付分配的商户号
weixinpay.mch_id=********
#接收微信支付异步通知回调地址，通知url必须为直接可访问的url，不能携带参数。
weixinpay.notify_url=***********

3.自定义对象

import org.springframework.boot.context.properties.ConfigurationProperties
import org.springframework.stereotype.Component

@ConfigurationProperties(prefix = "weixinpay")
@Component
class WeiXinPayConfig {

    var device_info: String? = null
    var fee_type: String? = null
    var appid: String? = null
    var mch_id: String? = null
    var notify_url: String? = null

    override fun toString(): String {
        return "WeiXinPayConfig(device_info=$device_info, fee_type=$fee_type, appid=$appid, mch_id=$mch_id, notify_url=$notify_url)"
    }

}

4.可直接使用

import com.lanhetech.paymodule.config.WeiXinPayConfig
import org.slf4j.LoggerFactory
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.RestController

@RestController
class PayModuleController {

    val logger = LoggerFactory.getLogger(this.javaClass)

    @Autowired
    var weiXinPayConfig: WeiXinPayConfig? = null

    @GetMapping("/payByWeiXin")
    fun payByWeiXin() {

        logger.info(weiXinPayConfig.toString())

    }

}
