Spring beans: ambiguous constructor when creating a bean -


first, apologize if has been answered elsewhere, @ loss how resolve error.

i have bean declaration as:

<bean id="prefix" class="java.lang.string"> <constructor-arg index="0"> <value>uio</value> </constructor-arg> </bean>

from defaultlistablebeanfactory, message printed:

creating shared singleton instance of instance of singleton bean 'prefix'.

after further messages, defaultlistablebeanfactory prints message:

ignoring constructor [public java.lang.string(byte..,int,int,java.nio.charset.charset .. then: unsatisifed dependency expressed through constructor argument index 1 of type[int]: ambiguous constructor.

i searched through web , saw similar type of question has been asked , answered few times, trying determine definitive answer is.

i tried following declarations:

<bean id="prefix" class="java.lang.string"> <constructor-arg index="0" type="string"> <value>uio</value> </constructor-arg> </bean>  <bean id="prefix" class="java.lang.string"> <constructor-arg index="0"> <value>"uio"</value> </constructor-arg> </bean>

to no avail.

i sure answer relatively simple , missing syntactic specification, have been unable find definitive syntactic structure work consistently.

any appreciated. guidance documentation of great help.

try 

<bean id="prefix" class="java.lang.string">     <constructor-arg type="java.lang.string" value="uio"/> </bean>
