java.lang.NoSuchMethodError: org.springframework.http.MediaType.getCharset()Ljava/nio/charset/Charset

Question

When I attempt to run my TestNG tests via ant I am getting java.lang.NoSuchMethodError: org.springframework.http.MediaType.getCharset()Ljava/nio/charset/Charset (see below for full exception)

I have no trouble compiling or running my web application but can't run tests via ant. I'm fairly certain this is a class loading issue but not sure what order class loading should be done at runtime. I'm using Spring 4.3.1 and Spring Security 4.1.1.

Is there a particular order to load my jars such that the "correct" version of org.springframework.http.MediaType is used?

Solution 1

Unbelievable...foiled by class loading issues once again...an uber jar named activemq-minimal-5.13.3.jar had references to spring jars in it that was causing the conflict. activemq-minimal-5.13.3.jar comes before spring alphabetically so the classes in that activemq jar were being loaded/used over the spring jars. Updated my ant build to load the spring classes first and now I'm all set.

The way I found out is I put all of my 3rd party libs together in a "Test" project and added/deleted jars (with somewhat of an inclination where the problem was) until I was able to pinpoint where the class loading issue was.

Solution 2

In spring latest version they have modified

org.springframework.http;

MediaType contentType = headers.getContentType();

Old :

      contentType.getCharSet()

New :

     contentType.getCharset()

Solution 3

org.springframework.http.MediaType.getCharset() was introduced since 4.3 if java did not find it that mean that you have a spring-core version below 4.3.1 in your classpath which get loaded and used.

@ZackMacomber Thanks for your response. getCharSet() got changed to getCharset() in spring-web 5.0.8. That's why I was getting this error.

Thank you for the update! Please "accept" your solution.

It worked for me . I updated the spring core version > 4.3

"Unbelievable...foiled by class loading issues once again..." -> uff, it's not only me who struggle once and once again with class loading issues with Spring, so it's not so obvious thing ;)

[Bhagwati Malav]

@Ankita I am using Spring 5.0.8, and getting same error nosuchmethod for getChaset.

[tom_mai78101]

I have encountered this error also. To fix my project setup, in my Maven POM file, all I did was move the <dependency> tag for activemq-all below all of the <dependency> tags for all Spring frameworks (spring-web, spring-core, etc.) I believed this is the same thing as re-ordering the dependencies around so that Spring framework jars are loaded first before activemq-all.

:-O Unbelievable! I was getting crazy because I didn't notice the case change from getCharSet() (in Spring 4.2) to getCharset() (in Spring 4.3+)!! And they even removed the old version, at least in Spring 5.2!
