一、该问题的重现步骤是什么？

1. 使用postgresql15.10数据库

2. 使用代码生成器生成代码

3.调用list方法，数据库中的字段为bigint8，但是传入的参数被转成了string

 Condition.getQueryWrapper(messageBox, MessageBoxEntity.class)

Caused by: org.postgresql.util.PSQLException: ERROR: operator does not exist: bigint = character varying

  建议：No operator matches the given name and argument types. You might need to add explicit type casts.

出现此错误

二、你期待的结果是什么？实际看到的又是什么？

SqlKeyword使用了Map传值，但是如此数据没有转成对应的数据类型，导致查询时候数据类型无法匹配。

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

boot商业版，winds本地机器

四、请提供详细的错误堆栈信息，这很重要。

org.springframework.jdbc.BadSqlGrammarException: 

### Error querying database.  Cause: org.postgresql.util.PSQLException: ERROR: operator does not exist: bigint = character varying

  建议：No operator matches the given name and argument types. You might need to add explicit type casts.

  位置：93

### The error may exist in com/eastfair/modules/exhibition/mapper/MessageBoxMapper.java (best guess)

### The error may involve defaultParameterMap

### The error occurred while setting parameters

### SQL: SELECT COUNT(*) AS total FROM internet_message_box WHERE is_deleted = 0 AND (recipient_user = ?)

### Cause: org.postgresql.util.PSQLException: ERROR: operator does not exist: bigint = character varying

  建议：No operator matches the given name and argument types. You might need to add explicit type casts.

  位置：93
