Yesterday, no, the day before yesterday
and roommates discuss why someone else's project into their own idea to run in an unsuccessful
start to say you need to configure these can not be directly imported
later to say their own way to import not
so awoke me
I Stupidly think that importing other people’s projects is called cross-platform, in fact, cross-platform and cross-operating systems
Then yesterday, I asked how Baidu csdn imported the project into eclipse. It
turned out that my own import method was wrong.
My import method was not loaded on the main class. I
learned a new method.
Some simple small project imports can run successfully.
Later, I imported the comprehensive case of the courses I learned and I
made a mistake. I was
puzzled. I
watched the video again and again.
Nothing wrong.
Later I prepared to delete and create and write the required classes on the original project. I
found that the class reported an error. I was
convinced.
Then I asked the teacher for help.
It turned out to be jdk. The environment is not right, the same is 1.8
but one is 192. The other is 184. I
learned the skills to reconfigure the jdk environment for the project.
Then I started tomcat
nice, and other people’s projects finally started successfully.
From then on I stood on the shoulders of giants and
did some alteration work, which is today
By the way, yesterday I wanted to change the background image of the jsp,
but it didn’t change.
I thought, it’s not enough to change the image. What do I need to configure?
Later, when I found the answer online, I
need to clear the browser cache. The
shortcut key is ctrl + shift + delete to
change the background image and it feels not as good as
it used to be. That project uses two images as the background.
I have been modifying the two images in ps, but I can’t do it all the time. It's a good fusion, I'm so angry
Today I regained my mood and
did some database modification work. I
mainly learned about the query method
of ssm. I modified the data in the database and replaced it with the data
I needed. I felt that I needed to learn the dictionary table
and found that it was easy. I can modify the data dictionary table too convenient
on the basis of the original database has added an own complete set of query conditions
that do, got a morning passed, no mess
to eat a meal
at noon to continue to watch, facing video Check one by one. In the
end, several details are not written, and some parameters have not been modified. The
most annoying thing is
that these things do not report errors, but the functions can
not
be realized. There is no way to start. I can only start from the logic of the code and the realization of the functions.
Fortunately,
I Succeeded
After the query function was completed, I was thinking of realizing a data visualization. I
remembered the previous garbage login interface.
I just modified the picture and added my own name.
No, I have to optimize it.
So I
went to the Internet to find div+css. The landing page
first realized the page effect,
and then inserted it into the login page of the existing project.
This also made a lot of mistakes.
Even though I am quite good at this
, the mistake was that I entered the correct user and password and failed to jump to the specified page,
so I
went again. I learned the video of the login page.
This is much simpler than the query function. It is
very fast and it is realized.
I am also quite satisfied.
Backend, java or something, I really don’t have a brain, what kind, implementation class, xml, really big head,
but the beautification of the front-end page is really fun,
but my roommate thinks the back-end is simple, and the front-end needs talent
.
Learn visualization on Monday, realize the project quickly, and then prepare for CET-6, come on!
