基于springBoot的责任链模式

在日常的业务处理中，责任链很常用，在此做记录

/**
* 校验调用链封装
*
* @author nanfengxiangbei
* @date 2022/3/7
*/
@Component
public class ToPayCheckerMaster extends ToPayAbstractChecker {

@Autowired
public ToPayCheckerMaster(ToPaySignChecker toPaySignChecker,
ToPayAccessChecker toPayAccessChecker) {
// 设置校验调用链（注意先后顺序）

// --签名校验
setNext(toPaySignChecker);

// -- 权限校验
toPaySignChecker.setNext(toPayAccessChecker);
}

/**
* 启动校验
*
* @param toPayBo 申请上下文
*/
@Override
public void check(ToPayBo toPayBo) {
checkNext(toPayBo);
}
}

/**
* 校验调用链抽象类
*
* @author nanfengxiangbei
* @date 2022/3/7
*/
public abstract class ToPayAbstractChecker {

/**
* 下一个校验对象
*/
protected ToPayAbstractChecker next;

/**
* 执行校验
*
* @param toPayBo 上下文
*/
public abstract void check(ToPayBo toPayBo);

protected void checkNext(ToPayBo toPayBo) {
if (toPayBo.getRespVo().getCode().equals(PayInterfaceStatusEnum.SUCCESS.getCode()) && next != null) {
next.check(toPayBo);
}
}

public void setNext(ToPayAbstractChecker next) {
this.next = next;
}
}

/**
* 签名校验
*
* @author nanfengxiangbei
* @date 2022/3/7
*/
@Component
public class ToPaySignChecker extends ToPayAbstractChecker {

private final Logger logger = LoggerFactory.getLogger(ToPaySignChecker.class);

@Reference
private ISecurityService securityService;

@NacosValue(value = "${toPay.signChecker.join}", autoRefreshed = true)
private boolean join;

/**
* 执行校验
*
* @param toPayBo 上下文
*/
@Override
public void check(ToPayBo toPayBo) {
if (join) {
doCheck(toPayBo);
} else {
logger.info("Sign checker not join");
}
//
checkNext(toPayBo);
}

private void doCheck(ToPayBo toPayBo) {
long startTime = System.currentTimeMillis();

logger.info("签名校验，结果：{}，耗时：{}", toPayBo.getRespVo().getCode(), System.currentTimeMillis() - startTime);
}

}

@Component
public class ToPayAccessChecker extends ToPayAbstractChecker {

private final Logger logger = LoggerFactory.getLogger(ToPayAccessChecker.class);

private static final String EQUITY_PRODUCT_APP_ID = "1000";

@NacosValue(value = "${toPay.accessPermChecker.join}", autoRefreshed = true)
private boolean join;

/**
* 执行校验
*
* @param toPayBo 上下文
*/
@Override
public void check(ToPayBo toPayBo) {
if (join) {
doCheck(toPayBo);
} else {
logger.info("Access Permission checker not join");
}
//
checkNext(toPayBo);
}

private void doCheck(ToPayBo toPayBo) {
long startTime = System.currentTimeMillis();

//
logger.info("结果：{}，耗时：{}", toPayBo.getRespVo().getCode(), System.currentTimeMillis() - startTime);
}

}
