wenn i Kamel Mybatis Komponente in meinem Projekt verwenden, fand ich, dass die Liste Parameter 'Liste' Name musscamel mybatis-Komponente unterstützt nur Listenparameter, der 'list' benennen muss?
Das folgende Beispiel funktioniert:
from(xxx)
...
...
.setHeader("list",simple("${body.OriginCodeList}"))
.to("mybatis:selectByInnerCodeList?statementType=SelectList&inputHeader=list")
Mybatis Mapper xml:
<select id="selectByInnerCodeList" resultMap="BaseResultMap" parameterType="java.util.List">
select
<include refid="Base_Column_List" />
from MF_FundManagerNew
WHERE Incumbent=1
<if test="list!=null and list.size()>0 ">
and InnerCode IN
<foreach collection="list" item="innerCodeSingle" open="(" close=")" separator=",">
#{innerCodeSingle}
</foreach>
</if>
</select>es Erfolg
Diese Route schlägt fehl
from(xxx)
...
...
.setHeader("innerCodeList",simple("${body.OriginCodeList}"))
.to("mybatis:selectByInnerCodeList?statementType=SelectList&inputHeader=innerCodeList")
Mybatis Mapper xml:
<select id="selectByInnerCodeList" resultMap="BaseResultMap" parameterType="java.util.List">
select
<include refid="Base_Column_List" />
from MF_FundManagerNew
WHERE Incumbent=1
<if test="innerCodeList!=null and innerCodeList.size()>0 ">
and InnerCode IN
<foreach collection="innerCodeList" item="innerCodeSingle" open="(" close=")" separator=",">
#{innerCodeSingle}
</foreach>
</if>
</select>Das zweite Beispiel wirft die folgende Ausnahme:

für Mybatis sein, wenn sie nur das Sammelobjekt Sie verbindlich sind, dann wäre es standardmäßig sein sein 'collection' oder' list'. Aber wenn du willst, kannst du die 'liste' in eine Map setzen und dann kann dein Map Key' innerCodeList' sein und MyBatis kann gegen den Schlüssel 'innerCodeList' auflösen. – MohamedSanaulla
Vielen Dank für deine Antwort. Es ist mein erstes Mal, hier eine Frage zu stellen, und es tut mir leid, dass ich auf Englisch schlecht bin. –
es funktioniert, wie Sie sagen, vielen Dank –
