Spring data JPA SpEL 条件操作

转载作者：行者123 更新时间：2023-12-01 23:51:05

我在存储库中有一个使用 Spring 表达式语言 (SpEL) 的查询:

@Query(value = "SELECT e from Estate e where e.loop >= ?#{#loop} AND e.loop <= ?#{#loop>4?10:#loop}")
Page<Estate> findAllThroughForeground(@Param("loop") short loop, Pageable pageable);

当loop小于5时，它工作得很好。但是，当loop大于5(包括5)时，我得到一个异常:

    java.lang.IllegalArgumentException: org.hibernate.QueryException: Not all named parameters have been set: [12] [SELECT e from Estate e where e.loop >= ?11 AND e.loop <= ?12]

我的spring-boot版本是1.5.2.RELEASE。

最佳答案

我以前遇到过类似的问题，它与 SpEL 中使用 short 有关。

当您的循环参数小于 5 时，它就会起作用，因为 e.loop (您的 short 或 Short 类型的字段实体)与loop(short类型的参数)进行比较。

当您的循环参数大于 5 时，它会中断，因为 e.loop (实体上的 short 或 Short 类型的字段) 与 10(SpEL 表达式中的 int 文字)进行比较。

异常消息没有那么有用，因为它提到了缺少的参数，而实际上只是参数值无法从 SpEL 表达式正确绑定(bind)。通过一些工作，可以深入挖掘并提取潜在的异常:

java.lang.IllegalArgumentException: Parameter value [10] did not match expected type [java.lang.Short (n/a)]

有几个选项可以解决此问题:

强制将 SpEL 表达式中的整数文字转换为短整型文字。可能有几种方法可以做到这一点，但最简单的是:

T(Short).parseShort(10)

它给你:

@Query(value = "SELECT e from Estate e where e.loop >= ?#{#loop} AND e.loop <= ?#{#loop > 4 ? T(Short).parseShort(10) : #loop}")

如果您能够修改实体，这可能是更好的选择。修改 loop 字段以使用 int 或 Integer:
```
@Column
private Integer loop;
```

如果将 loop 参数类型更改为 int，则现有查询应该可以正常工作:

    Page<Estate> findAllThroughForeground(@Param("loop") int loop, Pageable pageable);
