Examples with HotSwappableTargetSource org.springframework.aop.target.HotSwappableTargetSource used on opensource projects

Example 1 with HotSwappableTargetSource

use of org.springframework.aop.target.HotSwappableTargetSource in project spring-framework by spring-projects.

the class AbstractAopProxyTests method testExistingProxyChangesTarget.

@Test
public void testExistingProxyChangesTarget() throws Throwable {
    TestBean tb1 = new TestBean();
    tb1.setAge(33);
    TestBean tb2 = new TestBean();
    tb2.setAge(26);
    tb2.setName("Juergen");
    TestBean tb3 = new TestBean();
    tb3.setAge(37);
    ProxyFactory pc = new ProxyFactory(tb1);
    NopInterceptor nop = new NopInterceptor();
    pc.addAdvice(nop);
    ITestBean proxy = (ITestBean) createProxy(pc);
    assertEquals(nop.getCount(), 0);
    assertEquals(tb1.getAge(), proxy.getAge());
    assertEquals(nop.getCount(), 1);
    // Change to a new static target
    pc.setTarget(tb2);
    assertEquals(tb2.getAge(), proxy.getAge());
    assertEquals(nop.getCount(), 2);
    // Change to a new dynamic target
    HotSwappableTargetSource hts = new HotSwappableTargetSource(tb3);
    pc.setTargetSource(hts);
    assertEquals(tb3.getAge(), proxy.getAge());
    assertEquals(nop.getCount(), 3);
    hts.swap(tb1);
    assertEquals(tb1.getAge(), proxy.getAge());
    tb1.setName("Colin");
    assertEquals(tb1.getName(), proxy.getName());
    assertEquals(nop.getCount(), 5);
    // Change back, relying on casting to Advised
    Advised advised = (Advised) proxy;
    assertSame(hts, advised.getTargetSource());
    SingletonTargetSource sts = new SingletonTargetSource(tb2);
    advised.setTargetSource(sts);
    assertEquals(tb2.getName(), proxy.getName());
    assertSame(sts, advised.getTargetSource());
    assertEquals(tb2.getAge(), proxy.getAge());
}
