您可以在Eclipse中创建各种Java代码模板
窗口>首选项> Java >编辑器>模板
e.g.
Sysout扩展为:
System.out.println(${word_selection}${});${cursor}
您可以通过输入sysout加上CTRL+SPACE来激活它
您目前使用哪些有用的Java代码模板?包括它的名称和描述，以及为什么它很棒。
我正在寻找一个模板的原始/新颖的使用，而不是一个内置的现有功能。
创建Log4J日志记录器 从显示中获取swt颜色 Syncexec - Eclipse框架 单例模式/Enum单例生成 Readfile 常量 Traceout 格式字符串 注释代码审查 字符串格式 尝试最终锁定 消息格式i18n和log Equalsbuilder Hashcodebuilder Spring对象注入 创建FileOutputStream

List_methods——为列表生成添加、删除、计数和包含的方法
public void add${listname}(${listtype} toAdd){
get${listname}s().add(toAdd);
}
public void remove${listname}(${listtype} toRemove){
get${listname}s().remove(toRemove);
}
public ${listtype} get${listname}(int index){
return get${listname}s().get(index);
}
public int get${listname}Count(){
return get${listname}s().size();
}
public boolean contains${listname}(${listtype} toFind){
return get${listname}s().contains(toFind);

id——为简单的JPA @Id插入注释、导入、字段和getter
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
public Long getId(){
return id;
}
${cursor}
${:import (javax.persistence.GenerationType,javax.persistence.GeneratedValue,javax.persistence.Id)}

Bean属性
private ${Type} ${property};
public ${Type} get${Property}() {
return ${property};
}
public void set${Property}(${Type} ${property}) {
${propertyChangeSupport}.firePropertyChange("${property}", this.${property}, this.${property} = ${property});
}
PropertyChangeSupport
private PropertyChangeSupport ${propertyChangeSupport} = new PropertyChangeSupport(this);${:import(java.beans.PropertyChangeSupport,java.beans.PropertyChangeListener)}
public void addPropertyChangeListener(PropertyChangeListener listener) {
${propertyChangeSupport}.addPropertyChangeListener(listener);
}
public void addPropertyChangeListener(String propertyName, PropertyChangeListener listener) {
${propertyChangeSupport}.addPropertyChangeListener(propertyName, listener);
}
public void removePropertyChangeListener(PropertyChangeListener listener) {
${propertyChangeSupport}.removePropertyChangeListener(listener);
}
public void removePropertyChangeListener(String propertyName, PropertyChangeListener listener) {
${propertyChangeSupport}.removePropertyChangeListener(propertyName, listener);

下面是一个foreach，用于迭代List<Stuff>。循环中的可选内容用于查找列表中的元素并返回它。
for (${t:elemType(w)} elem: ${w:collection}) {
if (elem.get.equals(${localVar})){
return elem;
}
}
return null;
对于log，在成员变量中添加一个有用的小调。
private static Log log = LogFactory.getLog(${enclosing_type}.class);
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
