How to solve the error "Failed to load the JNI shared library jvm. dll" when you start Eclipse !, Jnijvm. dll

How to solve the error "Failed to load the JNI shared library jvm. dll" when you start Eclipse !, Jnijvm. dll
Cause 1: The jvm. dll does not exist in the specified directory.
Countermeasure: (1) reinstall jre or jdk and configure environment variables. (2) copy a jvm. dll file to this directory.
Cause 2: The version of eclipse is different from that of jre or jdk.
Countermeasure: either 64-bit or 32-bit, either 32-bit or 64-bit.
Cause 2 has a higher probability. Cause 1 is unlikely to happen.

Most people should be in the second case, and I am in the second case. When both jdk and tomcat are 32-bit, Eclipse also needs to select 32-bit. If you select a 64-bit Eclispe, the preceding error is reported. In a 64-bit windows system, a 32-bit jdk + tomcat + eclipse can also be used. Make sure thatJdk + tomcat + eclipse are both 32-bit and 64-bit.
