Quasar weaving is compiled or loaded. It is not possible to know whether the implementation class is suspendable, so it is necessary to explicitly specify
Method Instrument Implementation DetailsHere is the entire quasar fiber is the implementation of the principle of the most critical place, but also the most questionable place, we are interested to see the source code, about 1000 lines of ASM operation, can consolidate the knowledge of the JVM and in-depth understanding of the principle
container Network segment routes
Some of the specific commands to be implemented are as follows:For 10.211.55.3 settings
sudo ovs-vsctl show #ovs状态
sudo add-br obr0 #增加ovs网桥名为obr0
sudo ovs-vsctl add-port obr0 gre0
For 10.211.55.5 to Unicom 10.221.55.3 only need to set the routing table to:
Route
sudo ip route add 10.211.55.0/24 via 10.211.55.5 Dev eth0

One aspect of Spring Aop includes 1. Enhanced types (before and after function calls, throwing exceptions and before and after function calls) 2. Enhanced business logic 3. Connection point
Spring Aop only supports connection points for methods, and when I want to weave enhancements inside a method, there are two ways to do it:
1. For example, a function A has a,b,c three functions, I would like to be in the middle of a function before B also
Today's communication networks are composed of multiple interconnected optical and electrical components to support high-speed video, voice, and data transmission. The backbone of the network is optical fiber. Its design and manufacture are used to optimize attenuation and dispersion, making the network the most cost-effective and cost-effective network. A new optical fiber design is widely accepted in the global communication industry, that is, low water peak LWP) optical fiber. The low water p
page table, and the content of the corresponding address space is the level descriptor.The first-level descriptor is divided into the following types:
Coarse-grained Page table descriptor
Segment Descriptor
Fine-grained Page table descriptor
From the above three images, we can see that different types of descriptors are determined by the lowest 2 bits of the descriptor, respectively:

the final display logic code is generated on the first running dynamic page, and the generated htmL code is truncated and saved. The dynamic page is converted to a static page. When you access the page later, you can directly access the static page without the complicated calculation process of the dynamic page. The first step is to run the logic to display dynamic code generation, and the second step is to save the html code formed by the page logic.

, so that the program development will inevitably produce too many agents, and, all the agent operation in addition to the method called, the other operations are the same, then it is definitely a duplicate code at this time. The best way to solve this problem is to complete the proxy function through a proxy class, which must be done using dynamic proxy.Dynamic AgentCompared with the static proxy class, dynamic proxy class, the bytecode of dynamic proxy class is generated dynamically by the Jav
