Performance Optimization Tips for Trimou Core Framework in Java Class Libraries
Performance optimization skills of the Trimou Core framework in Java Library
The use of the Trimou Core framework in the Java library can help us handle template rendering tasks more efficiently.However, when using this framework, we need to pay attention to some performance optimization skills to ensure that our applications can achieve the best execution efficiency.This article will introduce some performance optimization techniques for the Trimou Core framework, and provide relevant Java code examples.
1. Reasonable use of cache
The Trimou Core framework provides a cache layer that can cache the compiled template to improve the rendering speed.In use, we should reasonably allocate and manage cache to avoid excessive cache's too many templates occupying too much memory, and at the same time, we must ensure that the templates that are often used can be quickly obtained.Below is an example of setting cache:
MustacheEngine engine = MustacheEngineBuilder.newBuilder()
.addTemplateLocator(new FileSystemTemplateLocator(1, Paths.get("templates"), "html"))
.setTemplateCache (New InMemoryConcurrentMapLateCache (100)) // Set the cache size of 100 templates
.build();
2. Reduce the number of template analysis times
To improve performance, we should try to avoid frequent template analysis.You can reduce the number of parsing by pre -compilation of templates and store them in memory.The following is an example of a pre -compiled template:
String templateContent = "<html>Hello {{name}}!</html>";
Template template = engine.compileMustache(templateContent, "myTemplate");
// After that, you can directly use the pre -compiled template for rendering
Writer writer = new StringWriter();
template.render(writer, data);
String renderedContent = writer.toString();
3. Avoid unnecessary template rendering
In some cases, we may only need to obtain a strings generated by the template, without writing it into a specific output stream.At this time, we can use the `RENDER` method of the` TemplateEnderer` to return the rendering result in the form of a string to avoid unnecessary IO operations.The following is an example:
String templateContent = "<html>Hello {{name}}!</html>";
String renderedContent = engine.getMustacheEngine().getTemplateRenderer().render(templateContent, data);
4. Use reasonable data structure
When preparing template data, we should use the appropriate data structure to improve access efficiency.Selecting the appropriate data structure can make the variables in the template look faster, thereby increasing the rendering speed.For example, using `hashmap` instead of` arrayList` can find template variables faster.
Map<String, Object> data = new HashMap<>();
data.put ("name", "Zhang San");
data.put("age", 25);
In summary, through a reasonable configuration cache, reducing the number of template resolution, avoiding unnecessary rendering, and using reasonable data structures, we can optimize performance and improve the efficiency of template rendering when using the Trimou core framework in the Java library.These techniques can help us better use the function of the Trimou Core framework in practical applications.
