Naming rules that should be paid attention to when using spring to inject JavaBean

Generally, when using spring to inject JavaBean, public void setuerdao (userdao) is used ).

Then, you can go to <property name = "uerdao"> <ref local = "userdao"/>.

The first parameter is the name of setxxx. The following figure shows the DaO name configured in spring. If your Dao name is userdao1. In your <property name = "uerdao"> <ref local = "userdao1"/>.

There is also an error caused by nonstandard naming, such as: public void setdbbasedao (dbbasedao Dao ).

In this example, the lower-case letters in front of Dao are used according to the previous configuration. This time will not work.

<Property name = "dbbasedao"> <ref local = "dbbasedao"/>.

At this time, you will still encounter problems according to the previous configuration method. Here we need to configure it like this

<Property name = "dbbasedao"> <ref local = "dbbasedao"/>.

Now, the dB of dbbasedao is used as a lowercase letter. The dB is relative to the user of Example 1, and then the basedao is relative to the DAO of Example 1. In this way, it is passed.
