Today, I will talk to you about how to solve the problem that springmvc cascading attributes can not be converted. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

There are two points to note.

1. In the xml file of mapper, the corresponding cascading fields are required, such as

Insert into tbl_admin (name,password,email,lockFlag, role) values (# {name}, # {password}, # {email}, # {lockFlag,jdbcType=INTEGER}, # {role.id,jdbcType=INTEGER})

In this case, role is a role, is an entity class, and is associated with admin users.

When adding users, you also need to add roles. The role here is # {role.id,jdbcType=INTEGER}, which must be cascaded with id.

two。 In the foreground jsp page, the path attribute must also be cascaded with id, as shown in

The springmvc tag is used here. Path must have the cascading field of id

Otherwise report that the String type cannot be converted to an error report of Role.

After reading the above, do you have any further understanding of how to solve the problem of unconvertible exceptions in springmvc cascading attribute handling? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
