By lake2 (http://lake2.0x54.org) With the development of technology, ASP database plug-in is nothing new. I believe you have also played this. Well, have you ever encountered the case where the inserted ASP code is split by spaces (that is, there is a space between each character inserted )? Now let's solve this problem. After analyzing the actual situation of multiple cases, I found that as long as the

3. call a class in action and inject the class into spring. In this class, the dao operation times: org. springframework. dao. invalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode. NEVER/MANUAL): Turn your Session into FlushMode. COMMIT/AUTO or remove 'readonly' marker from transaction definition. this error occurs. Cause: When S2SH is used in the project, OpenSessionInViewFilter is enabled to prevent loadi

We often operate on strings. Spring has implemented common processing functions. We can use the org. springframework. util. stringutils tool class to help us process strings.Tool classes are organized as follows:Stringutils. haslength (null) = falseStringutils. haslength ("") = falseStringutils. haslength ("") = trueStringutils. haslength ("hello") = trueStringutils. hastext (null) = falseStringutils. hastext ("") = falseStringutils. hastext ("") = fa

First implement the org. rut. util. algorithm. sortutil class (which will be used for each sort in the future ): Package Org. rut. util. algorithm; OK. Next we will start sorting; 1. Insert sorting: Package Org. rut. util. algorithm. support; 2. Bubble Sorting: Package Org. rut. util. algorithm. support;

I don't know why, when the Org file #+TITLE:xxx is contained, the export reports an error similar to the following:Wrong type argument: listp, #("xxx" 0 3 (:parent (#0)))The reason is not clear for the moment.The experiment found that emacs -q starting Emacs, that is, not enabling its own configuration, the Org mode export contains #+TITLE:xxx org files is no pro

A year ago, the plan was to develop a set of MDD tools to simplify R D, standardize and provideCodeQuality. The mdd I understand consists of four parts: First, modeling (data model and Object Model) Second, a set of universal generators (freemarker) Third, the company edition dedicated eclipse 4. High-quality code templates (long-term accumulation process) Steps 1 and 4 are the foundation, but they depend on steps 2 and 3. CommentsLet's t

If you see this article, you are expected to have encountered such a trap. When you appear to be the right code (should be the first encounter with similar code, these most rapeseed textbooks or networks) after a Thunderbolt roaster keyboard, with full of excitement running, but was ejected can ' t find the main class and so on similar dialog box, Look at the output information on the Eclipse console showin
