1. Caused by: java.lang.NoSuchMethodError: org.springframework.web.bind.annotation.RequestMapping.path()[Ljava/lang/String;
   解決方法：clean eclipse工程、重新新建Tomcat
2. jar包衝突
   解決方法：此處只解釋maven如何使用，本工程依賴leech-core，奈何leech-core依賴2.3.22-incubatin，只需要，再次引入你需要的版本即可。（在pom中檢視依賴關係，ide、構建工具不一致，但是是思路一樣）

<dependency>
 

    <groupId>org.freemarker</groupId>
    <artifactId>freemarker</artifactId>
    <version>2.3.25-incubating</version>
    </dependency>
<dependency>
  <groupId>com.sf.leech</groupId>
      <artifactId>leech-core</artifactId>
      <version
 
>2.0.1-SNAPSHOT</version>
      <exclusion>
        <groupId>org.freemarker</groupId>
        <artifactId>freemarker</artifactId>
        <version>2.3.22-incubating</version>
     </exclusion>
</dependency> 

３. Maven打包命令
Ａ：mvn versions:set -DnewVersion=2.0.1-SNAPSHOT
（-SNAPSHOT表示版本覆蓋，有重複版本無所謂，沒有這個-SNAPSHOT版本相同會報錯）
恢復原版本：mvn versions:revert
Ｂ：1.進入leech根目錄執行：
　　mvn clean source:jar package deploy -Dmaven.test.skip=true
　　2.進入leech-maven-plugin目錄執行：
　　mvn clean source:jar package deploy -Dmaven.test.skip=true
或者關係，跳過ｔｅｓｔ　　
Ｃ：OK: mvn versions:commit;
　　fail: mvn versions:revert;
4. ajax跨域問題

response.setHeader(“Access-Control-Allow-Origin”,”*”);
response.setHeader(“Access-Control-Allow-Headers”,”x-requested-with,ssi-token”);
response.setHeader(“Access-Control-Max-Age”,”3600”);
response.setHeader(“Access-Control-Allow-Methods”,”GET,POST,PUT,DELETE,OPTIONS”);
5. select in （select） 為NULL
SELECT *
FROM dbo.Table_A AS a
WHERE a.ID NOT IN ( SELECT b.ID
FROM dbo.Table_B AS b
WHERE b.ID IS NOT NULL ) –排除NULL值參較
運算子比較
5. quartz 載入 spring bean
xml配置

    <bean id="testSetJobDetailBean" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <property name="name" value="exampleJob" />
        <property name="jobClass" value="com.sf.web.quartz.TestSetQuartz" />
        <!-- 可以封裝各種資料到JobExecutionContext裡 -->
        <property name="jobDataAsMap">
            <map>
                <entry key="timeout" value="5"/>
            </map>
        </property>
    </bean>

    <bean id="testTaskTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="testSetJobDetailBean" />
        <property name="startDelay" value="10000"/>
        <property name="cronExpression" value="0 0/1 * * * ?" />
    </bean>

    <bean id="testSchedulerFactoryBean"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
         <property name="schedulerContextAsMap">    
            <map>    
                <!-- spring 管理的service需要放到這裡，才能夠注入成功 -->    
                <description>schedulerContextAsMap</description>    
                <entry key="testSetRunningServiceImpl" value-ref="testSetRunningServiceImpl"/>  
                <entry key="emailHttpGeneratorImpl" value-ref="emailHttpGeneratorImpl"/>  
            </map>    
        </property> 
        <property name="applicationContextSchedulerContextKey">    
            <value>applicationContext</value>    
        </property>    
        <property name="triggers">
            <list>
                <ref bean="testTaskTrigger" />
            </list>
        </property>
    </bean>
