中间件(16) : 神禹API网关[5]-http接口默认超时修改

说明 : 就是在网关往数据库里面插入超时时间时把默认的超时时间替换成成配置的时间 

 

版本

        org.apache.shenyu
        shenyu
        2.5.1-SNAPSHOT
    

引入fastjson依赖

            com.alibaba
            fastjson
            1.2.83
        

具体方法替换shenyu-admin的[org.apache.shenyu.admin.service.impl.RuleServiceImpl]的registerDefault方法

    public String registerDefault(final RuleDTO ruleDTO) {
        if (Objects.nonNull(ruleMapper.findBySelectorIdAndName(ruleDTO.getSelectorId(), ruleDTO.getName()))) {
            return "";
        }
        String handle = ruleDTO.getHandle();
        JSONObject jsonObject = JSONObject.parseObject(handle);
        if (jsonObject.containsKey("timeout")) {
            jsonObject.put("timeout", apiTimeout);
            ruleDTO.setHandle(jsonObject.toJSONString());
        }
        RuleDO ruleDO = RuleDO.buildRuleDO(ruleDTO);
        if (StringUtils.isEmpty(ruleDTO.getId())) {
            ruleMapper.insertSelective(ruleDO);
            addCondition(ruleDO, ruleDTO.getRuleConditions());
        }
        ruleEventPublisher.onRegister(ruleDO, ruleDTO.getRuleConditions());
        return ruleDO.getId();
    }
