JarCastingSpring beans graph
The beans-graph library creates a graph of the bean dependencies in your Spring application. The dependencies are collected at runtime. The library will help you:
- Find cyclic dependencies in your application
- Get an overview of your application's bean dependencies
Maven
Current version is 1.2.0.
<dependency>
<groupId>com.headstartech.beansgraph</groupId>
<artifactId>beansgraph-core</artifactId>
<version>1.2.0.RELEASE</version>
</dependency>
Basic usage
Java annotation configuration:
import com.headstartech.beansgraph.BeansGraphProducer;
import com.headstartech.beansgraph.ConsoleReporter;
import com.headstartech.beansgraph.EnableBeansGraph;
import org.springframework.stereotype.Component;
@EnableBeansGraph
@Component
public class ConfigureBeanGraphReporters implements BeansGraphConfigurer {
@Override
public void configureReporters(BeansGraphProducer producer) {
ConsoleReporter.forSource(producer).build();
}
}
The example above enables the beans graph producer (@EnableBeansGraph) and configures a reporter which prints the result to the default destination (System.out).
Filter on class name:
@Override
public void configureReporters(BeansGraphProducer producer) {
ConsoleReporter.forSource(producer)
.filter(new ClassNameFilter("com.foo"))
.build();
}
Dot reporter
To be able to generate an image with the dependencies, configure the dot reporter (http://en.wikipedia.org/wiki/DOT_%28graph_description_language%29).
Add dependency:
<dependency>
<groupId>com.headstartech.beansgraph</groupId>
<artifactId>beansgraph-dot-reporter</artifactId>
<version>1.2.0.RELEASE</version>
</dependency>
Configure:
@Override
public void configureReporters(BeansGraphProducer producer) {
DotReporter.forSource(producer)
.filter(new ClassNameFilter("org.foo.bar"))
.toOutput(new PrintWriter(new File("/tmp/dep.dot")))
.build();
}
