I want to inject a SecureRandom instance into an @Entity class, but when I check the value while running the debugger version of Tomcat, I only see a null value there. I don't get any error messages.
I have placed the spring-instrument-tomcat-3.2.5.RELEASE.jar into C:\apache-tomcat-7.0.40\lib and it seems to be picked up fine.

Entity class
I removed some extras to make this example clearer.
@Entity
@Configurable(preConstruction = true, autowire = Autowire.BY_TYPE)
public class Invitation {
@Id
@GeneratedValue
private int id;
@Transient
@Autowired
private SecureRandom random;
public Invitation(User owner, String inviteeEmail, String accessCode) {
if(accessCode == null) {
this.accessCode = generateAlphanumericAccessCode();
} else {
this.accessCode = accessCode;
}
this.owner = owner;
this.inviteeEmail = inviteeEmail;
}
private String generateAlphanumericAccessCode() {
return new BigInteger(130, random).toString(32);
}
}
Java Configuration Class
Again, removed extras to make this clearer.
@Configuration
@EnableWebMvc
@ComponentScan(basePackageClasses = RootContextConfig.class)
@EnableTransactionManagement
@EnableWebSecurity
@EnableAsync
@EnableSpringConfigured
@EnableLoadTimeWeaving(aspectjWeaving = EnableLoadTimeWeaving.AspectJWeaving.ENABLED)
public class RootContextConfig extends WebMvcConfigurerAdapter {
@Bean
public SecureRandom secureRandom() {
return new SecureRandom();
}
}
Context.xml (located in webapp/META-INF)
My webapp deploys to the root context in production and dev.
<?xml version="1.0" encoding="UTF-8"?>
<Context>
<Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>
