Spring Study Notes (6) AOP Eve [1] jdk dynamic proxy instance resolutionJDK dynamic proxy technology The most common application of dynamic proxy is AOP ). With AOP, we can obtain the methods, objects, input parameters, and response parameters when our program runs on a node, and dynamically add some new method logic before and after method calls, to meet our new needs, such as logging.There are two common

Describe A school gate outside the length of the road is a row of trees, every two adjacent trees between the interval is 1 meters. We can think of the road as a axis, one end of the road in the position of the axis 0, the other end in the position of L; each integral point on the axis, namely 0,1,2,......,l, is planted with a tree. There are some areas on the road to be used to build subways. These regions are represented by t

tutorial, we can do some cool shader, because the second part we'll start using the cool technology of multiple textures, normals, and so on. In the second part, we create a shader that implements the snow effect, modifying the model to show different effects depending on the extent of the snow. In the third part we improved our shader to mix the snow at the edge of the rock. In the fourth part, we use black edges and gradient textures to create a shader with a cartoon effect.

if there are cycle duplicate generation of new object entities.4. Check to see if there is a single query for all data in the database query. In general, if you take 100,000 records to memory at a time, you can cause a memory overflow. This problem is more covert, before the online, the database less data, not prone to problems, on-line, the database more data, a query may cause memory overflow. Therefore, query the database query as much as possible by paging.5. Check that the list, map, and o

Master checks and optimizes mysql Performance (16 ). I have been using the mysql tutorial database tutorial software, which is stable and highly efficient. When encountering severe performance problems, there are usually several possibilities: 1. I have never used the mysql tutorial database tutorial software for indexing, and it works stably and efficiently. There are several possible causes for serious performance problems:

Understand:We first use a popular analogy to understand the next generator, to the restaurant to eat, we ordered the menu, the chef is not a one-time dish are all up, but a dish. The chef here is a generator object. The builder is a Python feature, and Python uses the generator to support deferred operations, producing results only when they are good, rather than producing results immediately.1. Generator function: General function definition, return

the thread pool is closed or the task throws a runtimeexception.This shows that the basic principle of the thread pool is actually very simple, nothing more than pre-boot some threads, thread into the dead loop state, each time from the task queue to get a task to execute, until the thread pool is closed. If a thread terminates due to an exception executing a task, re-create a new thread. So repeated.In fact, the thread pool principle looks simple, but the complex is a variety of strategies, su

Describe There is an apple tree in the Tautau's yard, and 10 apples will be produced in every fall tree. When Apple matures, Tata will run to pick apples. Tata had a 30-centimetre-high bench, and when she couldn't pick it up with her hand, she would step on the bench and try again. Now that you know the height of 10 apples to the ground and the maximum height you can reach when the Tata handle is stretched, help Tata calculate the number of apples she can pick. If she tou

JS case 6-Waterfall stream layout (1)In actual projects, a waterfall flow layout is occasionally used. Waterfall flow layout is characterized by ensuring that content blocks do not have large gaps in the horizontal direction during multi-column layout, similar to the waterfall effect. To put it simply, in the vertical list, the content block is one by one. When the content is large and not fixed, it depends
