SpringBoot注解之@ConfigurationProperties

SpringBoot项目加载yml配置文件中的数据，可以把配置文件的信息，读取并自动封装成实体类，这样子，我们在代码里面使用就轻松方便多了，这时候，我们就可以使用@ConfigurationProperties，它可以把同类的配置信息自动封装成实体类。

列如，需要加载如下配置文件的中参数：

定义一个实体类与上面参数一一对应就可以了，如下：

@Component
@ConfigurationProperties(prefix="connection")
public class ConnectionSettings {

    private String platform;
    private String pageSize;
    private String platSysId ;
    private String uploadSaveDir ;
    private String uploadVisitBaseUrl ;
    private String restHosUrl ;
    private String restBdpUrl ;
    private String restNhsUrl ;
    private String restPayUrl ;
    private String manHosUrl ;
    private String manBdpUrl ;
    private String manNhsUrl ;

    public String getPlatform() {
        return platform;
    }

    public void setPlatform(String platform) {
        this.platform = platform;
    }

    public String getPageSize() {
        return pageSize;
    }

    public void setPageSize(String pageSize) {
        this.pageSize = pageSize;
    }

    public String getPlatSysId() {
        return platSysId;
    }

    public void setPlatSysId(String platSysId) {
        this.platSysId = platSysId;
    }

    public String getUploadSaveDir() {
        return uploadSaveDir;
    }

    public void setUploadSaveDir(String uploadSaveDir) {
        this.uploadSaveDir = uploadSaveDir;
    }

    public String getUploadVisitBaseUrl() {
        return uploadVisitBaseUrl;
    }

    public void setUploadVisitBaseUrl(String uploadVisitBaseUrl) {
        this.uploadVisitBaseUrl = uploadVisitBaseUrl;
    }

    public String getRestHosUrl() {
        return restHosUrl;
    }

    public void setRestHosUrl(String restHosUrl) {
        this.restHosUrl = restHosUrl;
    }

    public String getRestBdpUrl() {
        return restBdpUrl;
    }

    public void setRestBdpUrl(String restBdpUrl) {
        this.restBdpUrl = restBdpUrl;
    }

    public String getRestNhsUrl() {
        return restNhsUrl;
    }

    public void setRestNhsUrl(String restNhsUrl) {
        this.restNhsUrl = restNhsUrl;
    }

    public String getRestPayUrl() {
        return restPayUrl;
    }

    public void setRestPayUrl(String restPayUrl) {
        this.restPayUrl = restPayUrl;
    }

    public String getManHosUrl() {
        return manHosUrl;
    }

    public void setManHosUrl(String manHosUrl) {
        this.manHosUrl = manHosUrl;
    }

    public String getManBdpUrl() {
        return manBdpUrl;
    }

    public void setManBdpUrl(String manBdpUrl) {
        this.manBdpUrl = manBdpUrl;
    }

    public String getManNhsUrl() {
        return manNhsUrl;
    }

    public void setManNhsUrl(String manNhsUrl) {
        this.manNhsUrl = manNhsUrl;
    }
}
