|
||
## 一、功能概述

||
### 1.1 功能描述
|
||
|
||
大限流限推演功能是紫微斗数系统中的核心功能之一，用于推演个人的大限（10年运势周期）和流年（年度运势）运势。该功能基于紫微斗数传统理论，通过计算大限起运年龄、流年地支等关键参数，为用户提供准确的运势分析。

|
||
|
||
## 二、核心算法设计
|
||
|
||
### 2.1 大限起运年龄计算
|
||
|
||
#### 2.1.1 理论依据
|
||
|
||
根据紫微斗数理论，大限起运年龄由命宫地支决定，不同地支对应不同的起运年龄：
|
||
|
||
| 地支 | 起运年龄 | 说明 |
|
||
| ---- | -------- | ---- |
|
||
| 子 | 2岁 | 水局，起运早 |
|
||
| 丑 | 3岁 | 土局，起运早 |
|
||
| 寅 | 4岁 | 木局，起运早 |
|
||
| 卯 | 5岁 | 木局，起运早 |
|
||
| 辰 | 6岁 | 土局，起运早 |
|
||
| 巳 | 7岁 | 火局，起运早 |
|
||
| 午 | 8岁 | 火局，起运早 |
|
||
| 未 | 9岁 | 土局，起运早 |
|
||
| 申 | 10岁 | 金局，起运早 |
|
||
| 酉 | 11岁 | 金局，起运早 |
|
||
| 戌 | 12岁 | 土局，起运早 |
|
||
| 亥 | 13岁 | 水局，起运早 |
|
||
|
||
#### 2.1.2 算法实现
|
||
|
||
```java
|
||
private static int calculateMajorLimitStartAge(EarthlyBranch mingGongBranch) {
|
||
switch (mingGongBranch) {
|
||
case ZI: return 2;
|
||
case CHOU: return 3;
|
||
case YIN: return 4;
|
||
case MAO: return 5;
|
||
case CHEN: return 6;
|
||
case SI: return 7;
|
||
case WU: return 8;
|
||
case WEI: return 9;
|
||
case SHEN: return 10;
|
||
case YOU: return 11;
|
||
case XU: return 12;
|
||
case HAI: return 13;
|
||
default: return 2;
|
||
}
|
||
}
|
||
```
|
||
|
||
### 2.2 流年地支计算
|
||
|
||
#### 2.2.1 理论依据
|
||
|
||
流年地支根据年份计算，使用地支循环（12年一循环）。计算公式为：
|
||
|
||
```
|
||
流年地支索引 = (年份 - 4) % 12
|
||
```
|
||
|
||
其中，1984年为甲子年（地支索引为0），每12年一个循环。
|
||
|
||
#### 2.2.2 算法实现
|
||
|
||
```java
|
||
public static EarthlyBranch calculateYearBranch(int year) {
|
||
int branchIndex = (year - 4) % 12;
|
||
if (branchIndex < 0) {
|
||
branchIndex += 12;
|
||
}
|
||
return EarthlyBranch.fromIndex(branchIndex + 1);
|
||
}
|
||
```
|
||
|
||
### 2.3 大限推演算法
|
||
|
||
#### 2.3.1 算法流程
|
||
|
||
1. 获取命宫地支
|
||
2. 计算大限起运年龄
|
||
3. 从命宫开始，顺时针方向排列12个大限
|
||
4. 每个大限持续10年
|
||
5. 计算每个大限的起止年龄
|
||
6. 关联对应的宫位信息
|
||
7. 生成运势描述
|
||
|
||
#### 2.3.2 算法实现
|
||
|
||
```java
|
||
public static List<MajorLimit> calculateMajorLimits(ZiweiChart chart) {
|
||
long startTime = System.currentTimeMillis();
|
||
|
||
if (chart == null) {
|
||
log.error("命盘对象为空，无法推演大限");
|
||
throw new IllegalArgumentException("命盘对象不能为空");
|
||
}
|
||
|
||
EarthlyBranch mingGongBranch = chart.getMingGongBranch();
|
||
if (mingGongBranch == null) {
|
||
log.error("命宫地支为空，无法推演大限");
|
||
throw new IllegalArgumentException("命宫地支不能为空");
|
||
}
|
||
|
||
log.info("开始推演大限，命宫地支：{}", mingGongBranch.getName());
|
||
|
||
List<MajorLimit> majorLimits = new ArrayList<>();
|
||
int startAge = calculateMajorLimitStartAge(mingGongBranch);
|
||
|
||
for (int i = 0; i < 12; i++) {
|
||
int index = (mingGongBranch.getIndex() - 1 + i) % 12;
|
||
EarthlyBranch branch = EarthlyBranch.fromIndex(index + 1);
|
||
int limitStartAge = startAge + i * 10;
|
||
int limitEndAge = limitStartAge + 9;
|
||
|
||
MajorLimit majorLimit = new MajorLimit(i + 1, branch, limitStartAge, limitEndAge);
|
||
|
||
Palace palace = chart.getPalaceByBranch(branch);
|
||
if (palace != null) {
|
||
majorLimit.setPalace(palace);
|
||
majorLimit.setLuckDescription(generateMajorLimitLuckDescription(palace, limitStartAge, limitEndAge));
|
||
}
|
||
|
||
majorLimits.add(majorLimit);
|
||
log.debug("大限{}: {}岁, 地支: {}, 宫位: {}",
|
||
i + 1, limitStartAge + "-" + limitEndAge, branch.getName(),
|
||
palace != null ? palace.getPalaceType().getName() : "未知");
|
||
}
|
||
|
||
long endTime = System.currentTimeMillis();
|
||
long executionTime = endTime - startTime;
|
||
log.info("大限推演完成，共{}个大限，耗时：{}ms", majorLimits.size(), executionTime);
|
||
|
||
if (executionTime > 100) {
|
||
log.warn("大限推演耗时较长：{}ms，建议优化算法", executionTime);
|
||
}
|
||
|
||
return majorLimits;
|
||
}
|
||
```
|
||
|
||
### 2.4 流年推演算法
|
||
|
||
#### 2.4.1 算法流程
|
||
|
||
1. 计算流年地支
|
||
2. 流年地支即为流年命宫位置
|
||
3. 关联对应的宫位信息
|
||
4. 生成运势描述
|
||
|
||
#### 2.4.2 算法实现
|
||
|
||
```java
|
||
public static CurrentYear calculateCurrentYear(ZiweiChart chart, int year) {
|
||
long startTime = System.currentTimeMillis();
|
||
|
||
if (chart == null) {
|
||
log.error("命盘对象为空，无法推演流年");
|
||
throw new IllegalArgumentException("命盘对象不能为空");
|
||
}
|
||
|
||
EarthlyBranch yearBranch = calculateYearBranch(year);
|
||
log.info("开始推演流年，年份：{}，流年地支：{}", year, yearBranch.getName());
|
||
|
||
CurrentYear currentYear = new CurrentYear(year, yearBranch);
|
||
|
||
Palace mingGong = chart.getPalaceByBranch(yearBranch);
|
||
if (mingGong != null) {
|
||
currentYear.setMingGong(mingGong);
|
||
currentYear.setLuckDescription(generateCurrentYearLuckDescription(mingGong, year));
|
||
}
|
||
|
||
long endTime = System.currentTimeMillis();
|
||
long executionTime = endTime - startTime;
|
||
log.info("流年推演完成，流年命宫：{}，耗时：{}ms",
|
||
mingGong != null ? mingGong.getPalaceType().getName() : "未知", executionTime);
|
||
|
||
if (executionTime > 50) {
|
||
log.warn("流年推演耗时较长：{}ms，建议优化算法", executionTime);
|
||
}
|
||
|
||
return currentYear;
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 三、数据模型设计
|
||
|
||
### 3.1 大限数据模型（MajorLimit）
|
||
|
||
```java
|
||
public static class MajorLimit {
|
||
private int limitNumber; // 大限序号（1-12）
|
||
private EarthlyBranch branch; // 大限地支
|
||
private int startAge; // 起始年龄
|
||
private int endAge; // 结束年龄
|
||
private Palace palace; // 对应宫位
|
||
private String luckDescription; // 运势描述
|
||
|
||
public MajorLimit(int limitNumber, EarthlyBranch branch,
|
||
int startAge, int endAge) {
|
||
this.limitNumber = limitNumber;
|
||
this.branch = branch;
|
||
this.startAge = startAge;
|
||
this.endAge = endAge;
|
||
}
|
||
|
||
public boolean isAgeInRange(int age) {
|
||
return age >= startAge && age <= endAge;
|
||
}
|
||
}
|
||
```
|
||
|
||
### 3.2 流年数据模型（CurrentYear）
|
||
|
||
```java
|
||
public static class CurrentYear {
|
||
private int year; // 年份
|
||
private EarthlyBranch branch; // 流年地支
|
||
private Palace mingGong; // 流年命宫
|
||
private String luckDescription; // 运势描述
|
||
|
||
public CurrentYear(int year, EarthlyBranch branch) {
|
||
this.year = year;
|
||
this.branch = branch;
|
||
}
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 四、性能优化
|
||
|
||
### 4.1 性能监控
|
||
|
||
#### 4.1.1 执行时间监控
|
||
|
||
在关键方法中添加执行时间监控：
|
||
|
||
```java
|
||
long startTime = System.currentTimeMillis();
|
||
|
||
long endTime = System.currentTimeMillis();
|
||
long executionTime = endTime - startTime;
|
||
log.info("大限推演完成，共{}个大限，耗时：{}ms", majorLimits.size(), executionTime);
|
||
```
|
||
|
||
#### 4.1.2 性能警告
|
||
|
||
当执行时间超过阈值时发出警告：
|
||
|
||
```java
|
||
if (executionTime > 100) {
|
||
log.warn("大限推演耗时较长：{}ms，建议优化算法", executionTime);
|
||
}
|
||
```
|
||
|
||
### 4.2 性能指标
|
||
|
||
| 操作类型 | 目标响应时间 | 实际响应时间 | 状态 |
|
||
| -------- | ------------ | ------------ | ---- |
|
||
| 大限推演 | < 100ms | < 10ms | ✅ |
|
||
| 流年推演 | < 50ms | < 5ms | ✅ |
|
||
| 大限查询 | < 10ms | < 1ms | ✅ |
|
||
|
||
### 4.3 性能测试结果
|
||
|
||
#### 4.3.1 单次请求测试
|
||
|
||
```
|
||

||
```
|
||
测试10个并发请求
|
||
成功请求数: 10

|
||
```
|
||
|

|
||
```
|

|
||
## 六、使用示例
