Highlights of problems and solutions in STRUTS + spring + hibernate project framework construction (2)

Struts1.2 + spring2.0 + hibernate3.1 highlights of problems and solutions in project framework construction (2)

There are two bugs in the process of building a project using MySQL as a database:

Severe: servlet. Service () for servlet JSP threw exception

Analysis:
No getter Method for property userid of bean org.apache.struts.taglib.html. bean indicates in modules. login. the USERID attribute in the Form Design in JSP cannot be found in the corresponding actionform bean or the setter/getter Method

Solution:
Add the corresponding attributes and setter/getter methods to the actionform bean.

Analysis:
Table 'morecans. morecans _ customer' doesn' t exist indicates that hibernate cannot find the customer table. Here, the data table cannot be found because the database name morecans must be provided when connecting to MySQL.

Solution:
Remove customer. HBM. <class name = "com. morecans. test. pojo. customer "table =" customer "catalog =" morecans "> catalog =" morecans, you can solve this problem.
