IDEA部署tomcat8.5.35原始碼
阿新 • • 發佈:2019-01-06
1、下載tomcat原始碼,並將壓縮檔案解壓到指定的工作目錄
2、在tomcat目錄下,建立catalina-home目錄和pom.xml檔案
3、修改pom.xml檔案內容
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.apache.tomcat</groupId> <artifactId>Tomcat8.5</artifactId> <name>Tomcat8.5</name> <version>8.5</version> <build> <finalName>Tomcat8.5</finalName> <sourceDirectory>java</sourceDirectory> <testSourceDirectory>test</testSourceDirectory> <resources> <resource> <directory>java</directory> </resource> </resources> <testResources> <testResource> <directory>test</directory> </testResource> </testResources> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.3</version> <configuration> <encoding>UTF-8</encoding> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <dependency> <groupId>org.easymock</groupId> <artifactId>easymock</artifactId> <version>3.4</version> </dependency> <dependency> <groupId>ant</groupId> <artifactId>ant</artifactId> <version>1.7.0</version> </dependency> <dependency> <groupId>wsdl4j</groupId> <artifactId>wsdl4j</artifactId> <version>1.6.2</version> </dependency> <dependency> <groupId>javax.xml</groupId> <artifactId>jaxrpc</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>org.eclipse.jdt.core.compiler</groupId> <artifactId>ecj</artifactId> <version>4.5.1</version> </dependency> </dependencies> </project>
並將目錄中的conf和webapps資料夾複製到catalina-home目錄中
4、將tomcat匯入IDEA中。配置執行配置
新增VM options,即可執行
-Dcatalina.home=catalina-home -Dcatalina.base=catalina-home -Djava.endorsed.dirs=catalina-home/endorsed -Djava.io.tmpdir=catalina-home/temp -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=catalina-home/conf/logging.properties
報錯:執行之後如果Test測試程式碼報錯,可以把該相關類註釋掉,繼續執行專案,訪問http://localhost:8080,得到結果:
原因是我們直接啟動org.apache.catalina.startup.Bootstrap的時候沒有載入org.apache.jasper.servlet.JasperInitializer,從而無法編譯JSP。解決辦法是在tomcat的原始碼org.apache.catalina.startup.ContextConfig中的configureStart函式中手動將JSP解析器初始化:
protected synchronized void configureStart() {
// Called from StandardContext.start()
if (log.isDebugEnabled()) {
log.debug(sm.getString("contextConfig.start"));
}
if (log.isDebugEnabled()) {
log.debug(sm.getString("contextConfig.xmlSettings",
context.getName(),
Boolean.valueOf(context.getXmlValidation()),
Boolean.valueOf(context.getXmlNamespaceAware())));
}
webConfig();
//新增該行程式碼即可
context.addServletContainerInitializer(new JasperInitializer(), null);
if (!context.getIgnoreAnnotations()) {
applicationAnnotationsConfig();
}
if (ok) {
validateSecurityRoles();
}
// Configure an authenticator if we need one
if (ok) {
authenticatorConfig();
}
// Dump the contents of this pipeline if requested
if (log.isDebugEnabled()) {
log.debug("Pipeline Configuration:");
Pipeline pipeline = context.getPipeline();
Valve valves[] = null;
if (pipeline != null) {
valves = pipeline.getValves();
}
if (valves != null) {
for (int i = 0; i < valves.length; i++) {
log.debug(" " + valves[i].getClass().getName());
}
}
log.debug("======================");
}
// Make our application available if no problems were encountered
if (ok) {
context.setConfigured(true);
} else {
log.error(sm.getString("contextConfig.unavailable"));
context.setConfigured(false);
}
}
