下面的代码假设是异步工作,而是等待Async部分完成然后继续.如何使blah()方法异步运行？

@Path("/test")

public String tester()
{
return "Running...";
}
@GET
@Path("/triggerNew")
@Produces("text/plain")
public String triggerNew()
{
System.out.println("BEFORE " + new Date() + " BEFORE");
new Process().blah();
System.out.println("AFTER " + new Date() + " AFTER");
return "TRIGGERED";
}
}
Process.java
@Component
public class Process
{
@Async
public void blah()
{
try
{
Thread.currentThread().sleep(5000);
}
catch (InterruptedException e)
{
e.printstacktrace();
}
System.out.println("NEW THREAD " + new Date() + " NEW THREAD");
}
}
解决方法
@Async仅在注释Spring管理的bean而不是任意类时才有效.您需要将Process定义为Spring bean,然后将其注入您的控制器类,例如
<bean id="test" class="com.spring.test.Test">
<property name="process">
<bean class="com.spring.test.Process"/>
</property>
</bean>
public class Test {
private Process process;
public void setProcess(Process process) {
this.process = process;
}
...
public String triggerNew() {
process.blah();
}
}
