检查以下代码是否有问题: StringBuilder info = new StringBuilder(); if (CollectionUtils.isNotEmpty(adminCreateVO.getSalaryGroupResourceList())){ for (SalaryGroupResourceVO salaryGroupResourceVO : adminCreateVO.getSalaryGroupResourceList()) { StringBuilder salaryGroupName = new StringBuilder("【" + salaryGroupMap.get(salaryGroupResourceVO.getSalaryGroupId()) + "】"); for (SalaryGroupIdentityVO resourceIdentity : salaryGroupResourceVO.getResourceIdentities()) { if (!Objects.equals(resourceIdentity.getName(), SalaryGlobalConstants.PAYROLL_GROUP_MANAGEMENT_SALARY_APPROVAL)){ salaryGroupName.append(resourceIdentity.getName()).append("、"); } } info.append(salaryGroupName.substring(0, salaryGroupName.length() - 1)).append(";"); } }

代码看起来没有明显的语法错误,但可能存在逻辑上的问题。以下是一些需要注意的地方:
1. `CollectionUtils.isNotEmpty()`是Apache Commons Collections库中的方法,用于检查集合是否不为空。请确保你已经导入了正确的库,并正确使用该方法。
2. 在循环中,你使用了`salaryGroupMap.get(salaryGroupResourceVO.getSalaryGroupId())`来获取`salaryGroupId`对应的值。请确保`salaryGroupMap`已经被正确初始化,并且包含了所需的键值对。
3. 在`salaryGroupName.append(resourceIdentity.getName()).append("、")`这一行,你将每个`resourceIdentity.getName()`都添加到了`salaryGroupName`中,并在后面添加了一个逗号。但请注意,在最后一个元素后面不需要添加逗号。因此,在使用`info.append(salaryGroupName.substring(0, salaryGroupName.length() - 1)).append(";")`之前,你应该检查一下`salaryGroupName`的长度是否大于1,以避免出现空指针异常。
希望这些提示对你有帮助!如果你有任何其他问题,请随时提问。

fun getAddressFromLocation(context: Context,latitude: Double, longitude: Double): String? { val geocoder = Geocoder(context, Locale.getDefault()) val addresses: List<Address>? var addressText = "" try { addresses = geocoder.getFromLocation(latitude, longitude, 1) if (addresses != null && addresses.isNotEmpty()) { val address = addresses[0] val sb = StringBuilder() for (i in 0..address.maxAddressLineIndex) { sb.append(address.getAddressLine(i)).append("\n") } addressText = sb.toString().trim() } } catch (e: IOException) { e.printStackTrace() } return addressText }这个代码如何只获取市
您可以在获取地址的循环中判断地址的类型,如果是市级地址,就只获取对应的部分即可。以下是修改后的代码示例:
```kotlin
fun getCityFromLocation(context: Context, latitude: Double, longitude: Double): String? {
val geocoder = Geocoder(context, Locale.getDefault())
val addresses: List<Address>?
var city = ""
try {
addresses = geocoder.getFromLocation(latitude, longitude, 1)
if (addresses != null && addresses.isNotEmpty()) {
val address = addresses[0]
val sb = StringBuilder()
for (i in 0..address.maxAddressLineIndex) {
val addressLine = address.getAddressLine(i)
if (addressLine.contains("市")) {
city = addressLine
break
}
}
}
} catch (e: IOException) {
e.printStackTrace()
}
return city
}
```
在上述代码中,我添加了一个判断,如果地址中包含"市"字,就将该地址赋值给city变量并跳出循环。这样就只获取了市级地址。注意,这里假设返回的地址列表中第一个地址就是最精确的地址,如果需要更多精确度,请根据实际情况进行调整。
两个集合的数据有上万条,导出内存溢出,请将下面的代码优化 for (int i = 0; i <ls.size() ; i++) { Map<String,Object> sb1=new HashMap<>(); Map<String,Object> sb2=new HashMap<>(); boolean sbboolean1=false; boolean sbboolean2=false; for (int j = 0; j <list2.size() ; j++) { if(StringUtils.isNotEmpty(ls.get(i).getSalesorder())&&StringUtils.isNotEmpty(list2.get(j).getSalesorder())){ if(ls.get(i).getSalesorder().trim().equals(list2.get(j).getSalesorder().trim())){ if(StringUtils.isNotEmpty(list2.get(j).getDeliveryresponse())){ sbboolean1=true; sb1.put(list2.get(j).getDeliveryresponse().trim(),null); } if(StringUtils.isNotEmpty(list2.get(j).getOrderdate())){ sbboolean2=true; sb2.put(list2.get(j).getOrderdate().trim(),null); } } } } if(sbboolean1){ StringBuilder sbdate1=new StringBuilder(); for (String s:sb1.keySet()) { sbdate1.append(s+" "); } ls.get(i).setLowmaterialstatusb(sbdate1.toString()); } if(sbboolean2){ StringBuilder sbdate2=new StringBuilder(); for (String s:sb2.keySet()) { sbdate2.append(s+" "); } ls.get(i).setLowmaterialstatus(sbdate2.toString()); } }
这段代码可以进行以下优化:
1. 避免在循环中频繁调用 `ls.get(i)` 和 `list2.get(j)` 方法,可以先将它们的值存储在变量中:
```
for (int i = 0; i < ls.size(); i++) {
Map<String, Object> sb1 = new HashMap<>();
Map<String, Object> sb2 = new HashMap<>();
boolean sbboolean1 = false;
boolean sbboolean2 = false;
Object salesorder1 = ls.get(i).getSalesorder();
if (StringUtils.isNotEmpty(salesorder1)) {
String salesorder1Trim = salesorder1.toString().trim();
for (int j = 0; j < list2.size(); j++) {
Object salesorder2 = list2.get(j).getSalesorder();
if (StringUtils.isNotEmpty(salesorder2)) {
String salesorder2Trim = salesorder2.toString().trim();
if (salesorder1Trim.equals(salesorder2Trim)) {
Object deliveryresponse = list2.get(j).getDeliveryresponse();
if (StringUtils.isNotEmpty(deliveryresponse)) {
sbboolean1 = true;
sb1.put(deliveryresponse.toString().trim(), null);
}
Object orderdate = list2.get(j).getOrderdate();
if (StringUtils.isNotEmpty(orderdate)) {
sbboolean2 = true;
sb2.put(orderdate.toString().trim(), null);
}
}
}
}
}
// ...
}
```
2. 如果 `sb1` 和 `sb2` 中存储的值只需要是键的集合,可以使用 `HashSet` 代替 `HashMap`,避免在循环中频繁创建和销毁 value 对象:
```
for (int i = 0; i < ls.size(); i++) {
Set<String> sb1 = new HashSet<>();
Set<String> sb2 = new HashSet<>();
boolean sbboolean1 = false;
boolean sbboolean2 = false;
Object salesorder1 = ls.get(i).getSalesorder();
if (StringUtils.isNotEmpty(salesorder1)) {
String salesorder1Trim = salesorder1.toString().trim();
for (int j = 0; j < list2.size(); j++) {
Object salesorder2 = list2.get(j).getSalesorder();
if (StringUtils.isNotEmpty(salesorder2)) {
String salesorder2Trim = salesorder2.toString().trim();
if (salesorder1Trim.equals(salesorder2Trim)) {
Object deliveryresponse = list2.get(j).getDeliveryresponse();
if (StringUtils.isNotEmpty(deliveryresponse)) {
sbboolean1 = true;
sb1.add(deliveryresponse.toString().trim());
}
Object orderdate = list2.get(j).getOrderdate();
if (StringUtils.isNotEmpty(orderdate)) {
sbboolean2 = true;
sb2.add(orderdate.toString().trim());
}
}
}
}
}
// ...
}
```
3. 如果需要把 `sb1` 和 `sb2` 中的值拼接成字符串并赋值给对象的属性,可以直接使用 `String.join()` 方法,避免使用 `StringBuilder`:
```
for (int i = 0; i < ls.size(); i++) {
Set<String> sb1 = new HashSet<>();
Set<String> sb2 = new HashSet<>();
boolean sbboolean1 = false;
boolean sbboolean2 = false;
Object salesorder1 = ls.get(i).getSalesorder();
if (StringUtils.isNotEmpty(salesorder1)) {
String salesorder1Trim = salesorder1.toString().trim();
for (int j = 0; j < list2.size(); j++) {
Object salesorder2 = list2.get(j).getSalesorder();
if (StringUtils.isNotEmpty(salesorder2)) {
String salesorder2Trim = salesorder2.toString().trim();
if (salesorder1Trim.equals(salesorder2Trim)) {
Object deliveryresponse = list2.get(j).getDeliveryresponse();
if (StringUtils.isNotEmpty(deliveryresponse)) {
sbboolean1 = true;
sb1.add(deliveryresponse.toString().trim());
}
Object orderdate = list2.get(j).getOrderdate();
if (StringUtils.isNotEmpty(orderdate)) {
sbboolean2 = true;
sb2.add(orderdate.toString().trim());
}
}
}
}
}
if (sbboolean1) {
ls.get(i).setLowmaterialstatusb(String.join(" ", sb1));
}
if (sbboolean2) {
ls.get(i).setLowmaterialstatus(String.join(" ", sb2));
}
}
```
