对象私有属性上可缓存注释的条件

Question

@Cacheable(cacheNames = "detailedData", key = "#id", condition = "#currentPackage.getSellingPrice() > -1")
public Map<String, Object> getDetailedTestData(int id,PackageEntity currentPackage) {
/**
some code
*/
}

public class PackageEntity {

    private int sellingPrice;

    public int getSellingPrice() {
        return sellingPrice;
    }

    public void setSellingPrice(int sellingPrice) {
        this.sellingPrice = sellingPrice;
    }
  /**
  some other fields and their getter/setter
  */
}

Answer 1

如果指定的字段是私有的，SpEL似乎也会查找该字段的公共getter。

因此字段可以是公共的,也可以有公共getter

@Cacheable(cacheNames = "detailedData", key = "#id", condition ="#currentPackage.sellingPrice > -1")
public Map<String, Object> getDetailedTestData(int id,PackageEntity currentPackage) {
  /**
    some code
  */
}

所以上面的代码对我来说工作正常。
