从向量到数组

${array_type}[] ${v:var(Vector)}Array = new ${array_type}[${v}.size()];
${v}.copyInto(${v}Array);

在当前范围内抛出一个变量IllegalArgumentException (illarg):

throw new IllegalArgumentException(${var});

更好的

throw new IllegalArgumentException("Invalid ${var} " + ${var});  

我最喜欢的几个是……

1: Javadoc，插入关于该方法是Spring对象注入方法的文档。

 Method to set the <code>I${enclosing_type}</code> implementation that this class will use.
* 
* @param ${enclosing_method_arguments}<code>I${enclosing_type}</code> instance 

2:调试窗口，创建FileOutputStream并将缓冲区的内容写入文件。 用于当你想要比较缓冲区与过去的运行(使用BeyondCompare)，或者如果你不能查看缓冲区的内容(通过inspect)，因为它太大…

java.io.FileOutputStream fos = new java.io.FileOutputStream( new java.io.File("c:\\x.x"));
fos.write(buffer.toString().getBytes());
fos.flush();
fos.close();

春天注入

我知道这有点晚了，但这里是我在一个类中使用的Spring Injection:

${:import(org.springframework.beans.factory.annotation.Autowired)}
private ${class_to_inject} ${var_name};

@Autowired
public void set${class_to_inject}(${class_to_inject} ${var_name}) {
  this.${var_name} = ${var_name};
}

public ${class_to_inject} get${class_to_inject}() {
  return this.${var_name};
}

我知道我是在找死，但为了完成起见，我想分享这个:

单例生成模板的正确版本，克服了有缺陷的双重检查锁定设计(上面讨论过，其他地方也提到过)

单例创建模板: 命名为createsingleton

static enum Singleton {
    INSTANCE;

    private static final ${enclosing_type} singleton = new ${enclosing_type}();

    public ${enclosing_type} getSingleton() {
        return singleton;
    }
}
${cursor}

访问使用上述方法生成的单例对象:

单例引用模板: 命名这个getsingleton:

${type} ${newName} = ${type}.Singleton.INSTANCE.getSingleton();

使用Mockito创建一个mock(在“Java语句”上下文中):

${:importStatic('org.mockito.Mockito.mock')}${Type} ${mockName} = mock(${Type}.class);

在“Java类型成员”中:

${:import(org.mockito.Mock)}@Mock
${Type} ${mockName};

模拟void方法抛出异常:

${:import(org.mockito.invocation.InvocationOnMock,org.mockito.stubbing.Answer)}
doThrow(${RuntimeException}.class).when(${mock:localVar}).${mockedMethod}(${args});

模拟一个void方法来做一些事情:

${:import(org.mockito.invocation.InvocationOnMock,org.mockito.stubbing.Answer)}doAnswer(new Answer<Object>() {
public Object answer(InvocationOnMock invocation) throws Throwable {
    Object arg1 = invocation.getArguments()[0];
    return null;
}
}).when(${mock:localVar}).${mockedMethod}(${args});

验证被模拟的方法被精确地调用一次:

${:importStatic(org.mockito.Mockito.verify,org.mockito.Mockito.times)}
verify(${mock:localVar}, times(1)).${mockMethod}(${args});

验证mock方法从未被调用:

${:importStatic(org.mockito.Mockito.verify,org.mockito.Mockito.never)}verify(${mock:localVar}, never()).${mockMethod}(${args});

使用谷歌Guava的新链表(hashset和hashmap也类似):

${import:import(java.util.List,com.google.common.collect.Lists)}List<${T}> ${newName} = Lists.newLinkedList();

我还使用了一个生成Test类的巨大模板。下面是一个简短的片段，每个感兴趣的人都应该定制:

package ${enclosing_package};

import org.junit.*;
import static org.junit.Assert.*;
import static org.hamcrest.Matchers.*;
import static org.mockito.Matchers.*;
import static org.mockito.Mockito.*;
import org.mockito.Mockito;
import org.slf4j.Logger;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.runners.MockitoJUnitRunner;
import org.junit.runner.RunWith;

// TODO autogenerated test stub
@RunWith(MockitoJUnitRunner.class)
public class ${primary_type_name} {

    @InjectMocks
    protected ${testedType} ${testedInstance};
    ${cursor}

    @Mock
    protected Logger logger;

    @Before
    public void setup() throws Exception {
    }

    @Test
    public void shouldXXX() throws Exception {
        // given

        // when
        // TODO autogenerated method stub

        // then
        fail("Not implemented.");
    }
}
// Here goes mockito+junit cheetsheet
