在springboot2.0的配置文件yml自定义数组或List集合

#### 自定义List集合，首先在application.yml文件中配置

custom:
  mail[0]:
    username: xxx@xxx.com
    password: axxx
  mail[1]:
    username: xxx@xxx.com
    password: axxx

然后配置接受类

@Configuration
@ConfigurationProperties("custom")
public class Custom {

    private List<MailInfo> mail;

    public List<MailInfo> getMail() {
        return mail;
    }

    public void setMail(List<MailInfo> mail) {
        this.mail = mail;
    }


}

MailInfo类的内容是

 public class MailInfo {

    private String username;
    private String password;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

#### 自定义数组，首先在application.yml文件中配置

custom:
  ignored-token-path: /base/xx/login, /xx/**, /xx/hfc/test
  ignored-role-path: /base/xx/logout, /base/xx/queryMenus

然和配置接受类

@Configuration
@ConfigurationProperties("custom")
public class Custom {

    private String[] ignoredTokenPath;
    private String[] ignoredRolePath;

    public String[] getIgnoredTokenPath() {
        return ignoredTokenPath;
    }

    public void setIgnoredTokenPath(String[] ignoredTokenPath) {
        this.ignoredTokenPath = ignoredTokenPath;
    }

    public String[] getIgnoredRolePath() {
        return ignoredRolePath;
    }

    public void setIgnoredRolePath(String[] ignoredRolePath) {
        this.ignoredRolePath = ignoredRolePath;
    }
}
