Lightweight containers have recently been surging in the Java community, and these containers have been able to build a cohesive application from different projects. These containers are based on a common pattern, which determines how the container completes the assembly of components, which people call the "control inversion" "inversion of". This article will delve into the w

The Web. config file usually includes settings that must be different based on the running environment of the application. For example, when deploying the Web. config file, you may have to change the database connection string or disable debugging. ASP. NET provides some tools for Web application projects to automatically change (convert) The Web. config file when deploying these projects. For each environment to be deployed, you will create a conversion file, which only specifies the difference

Spring and Other lightweight containers can help developers assemble components from different projects into a cohesive application .. There is the same mode behind them. This mode determines how these containers assemble components. People refer to this pattern with a big name: "inversion ofcontrol, IOC ). give it a more descriptive name-dependency injection, and compare it with the service locator pattern. However, the difference between the two is
Servant Locator
The function of the ASM table (Servant Activity Mapping table) is described before. But he also has some limitations, because if you're using the adapter's ASM to map ice objects to servents, there are some effects: (1) Each Ice object has a different servant representation. (2) All Servants of all ice objects are permanently out of memory. If there is a large number of servant objects, then the server will be under great pressure, pe

In our actual project development, we often encounter the situation of creating the same class multiple times. If we use the general method to create a new class, every time we create a new class, an instance is generated, and there is no problem with small systems, but when the system

load the clob into an oracle tablespace, but the disadvantage is that the clob is outside of Oracle, and it cannot be managed (backed-up, kept consistent) is if the clob resided inside a table. see here, how to store image files into ORACLE tables. bfile is fastest because the clob is never really loaded into a tablespace, it's still outside oracle in a flat file.
Store the clob inside the table-The third option is to use a PL/SQL procedure to store the clob directly into an oracle table, and
